First compare the number of people staying with your listing maximum. If the larger group is within that limit, document the total in Airbnb messages and send a formal trip change that updates the guest count and price; on Vrbo, request payment and, once payment has fully settled and after check-in, update the guest count. If the group exceeds the maximum, an extra fee does not make the stay acceptable. Airbnb's Terms say, “You may not exceed the maximum number of allowed Guests.” Do not substitute cash or a payment app for the platform process.
I reduce the first decision to three numbers: booked guests, people actually staying overnight, and the listing maximum. Suppose 3 guests are booked, 5 plan to stay, and the maximum is 6. That can move to a formal change. If 6 are booked, 8 arrive, and the maximum is 6, charging more does not cure the capacity problem; the 2 additional people cannot stay.
Airbnb's ground rules state, “Approved guests: Guests should respect the approved number of guests and should ask their host if they’re unsure about the rules for visitors.” Keep the question factual and in the message thread. Identity and background checks have separate limits, which I cover in this guide to guest screening tools for Airbnb hosts.
An included count sets how many guests the base price covers. An extra guest fee applies above that count. The maximum is the hard ceiling. Airbnb says, “You can choose how many guests can book your home before an extra guest fee is charged.” That threshold is not permission to go beyond the listing maximum.
| Setting | Example | What it controls |
|---|---|---|
| Included guest count | 2 guests | The number covered by the base price |
| Extra-fee band | Guests 3 through 6 | When the configured per-guest charge applies |
| Maximum guest count | 6 guests | The most overnight guests the property allows |
Vrbo likewise treats capacity as a house rule: “Maximum overnight guests: Set the number of guests allowed to sleep on your property, including adults and children.” For an illustrative worksheet, say one additional guest creates $6 of laundry, $4 of consumables, and $8 of cleaner time per night. The direct cost is $18; the host still chooses the margin and checks how the platform displays the charge. For broader cost context, see Airbnb service fees and Vrbo fees for hosts.
Check the maximum and any laws, rules, regulations, or third-party contracts that apply to the listing before discussing money. Then confirm the new total in Airbnb messages. For example: “Your reservation is for 2 guests, and you are asking to make it 3 for all 4 nights. I’ll send a trip change for you to review.” Airbnb's instruction is direct: “If you can accommodate the larger group, send your guest a trip change that includes the additional cost per night for the extra guests.”
If the configured illustrative fee is $18 per extra guest per night, 1 added guest for 4 nights is 1 × 4 × $18 = $72 before any platform-calculated effects shown in the preview. I would trust the preview for the final total rather than predict taxes or service-fee treatment. Hosts who want the larger booking-and-payout context can start with how Airbnb works for owners.
Answering guests at 11pm is the part software should do.

Airbnb says, “Any changes you make to the guest count will apply to the entire reservation.” Suppose a reservation lasts 7 nights but the additional person plans to join only on nights 6 and 7. At an illustrative $18 per night, a guest-count change may show 1 × 7 × $18 = $126, not the 1 × 2 × $18 = $36 the parties expected for the partial stay.
Review the new total before sending anything. If you have difficulty changing the reservation because of extra guests, Airbnb says you can contact Support; do not invent an informal split. The fee-setting page also says, “Your new fee only applies to future reservations.” For an already confirmed booking, the same page states, “If you want to add an extra guest fee to a confirmed reservation, you’ll need to send your guest a trip change to adjust the price.”
Start with verification, not an accusation or an invoice. Say the reservation shows 3 guests and a policy-compliant observation suggests 5 people may be staying. Ask whether all 5 are overnight guests or whether 2 are visitors. That distinction matters because the platform's approved headcount and your disclosed visitor rule are not the same thing.
Do not promise a particular refund or collection outcome; Airbnb's page on when guests want to bring more people to your home says any refund follows the cancellation policy. Do not attempt physical removal. If there is immediate danger, contact local emergency services. For routine communication before and during a stay, these Airbnb guest message templates show how to keep requests short and documented.
Capacity comes before price. Airbnb explains that “Other Hosts might have a strict limit on the capacity for their home and can’t accommodate any more people.” If a home has a maximum of 6 and 8 people intend to stay, it cannot accommodate the group as proposed. I would not raise the maximum in exchange for money.
Airbnb tells hosts, “If you’re unable to accommodate the larger number of guests, let your guest know that your place isn’t the right fit for their group, and ask them to cancel their reservation.” Any refund then follows the applicable process and policy; the quote is not a promise of a particular refund or payout.
If the maximum comes from a permit, fire rule, building or HOA document, or insurance condition, check the governing source and your insurer. For example, a listing maximum of 6 does not override a local permit that allows only 4. Airbnb notes that some places have landlord-tenant, rent-control, and eviction laws that may apply to longer stays, and says to check local rules or seek legal advice.
Airbnb's current rule says, “Hosts aren’t permitted to collect any fees related to Airbnb reservations outside of our platform, unless expressly authorized by us.”
Airbnb documents limited exceptions and a Resolution Center route for certain optional fees on that page. For a confirmed reservation, Airbnb says to send a trip change to adjust the price.
Say a guest offers $40 a night in cash for a third person on a 4-night stay: that is $160 offered outside Airbnb. I would decline it and send the formal trip change instead.
Airbnb says, “The original total and the new total will be shown to guests before they accept your trip change request.” An agreeable message is not the same as formal acceptance.
For a cooperative correction before a 4:00 PM arrival: “Thanks for confirming 4 guests instead of the 3 booked. The maximum is 6. I’ve sent the trip change; please accept it before the additional guest arrives.” If the guest refuses: “The reservation still shows 3 guests. I cannot approve a 4th overnight guest unless the trip change is accepted. If you do not accept it before check-in, the additional person cannot stay.”
If the extra person is already inside, restate the facts, give a situation-appropriate response time in the message thread, and contact Airbnb Support. If 7 people are present at a home with a maximum of 6, the request for 1 person to leave rests on the capacity limit, not on whether the charge was paid. Keep any later review or report honest and separate from the negotiation; never use it as a threat.
Response speed and calendar hygiene, handled for you.
Start free — first 500 messagesOr book a demo callDo not copy Airbnb's buttons into a Vrbo case. Vrbo categorizes “Standard fees: For extra guests, cleaning, and pets.” It also says, “Changes to fees only apply to future bookings.” For an existing reservation, its instruction is: “To add a charge to an existing reservation, send the guest a payment request before their stay is complete.”
Use this order: confirm the larger group remains within the maximum, agree on the price in Vrbo messages, and send the payment request before the stay is complete. Vrbo says reservation updates are available only after the traveler’s payment has fully settled, and the number of guests can be updated after check-in. Suppose 2 guests were booked, the new total is 4, the maximum is 6, the stay is 3 nights, and the illustrative fee is $15 per extra guest per night. The request is 2 × 3 × $15 = $90.
Payment is a separate step. Vrbo says, “Extra payment requests are not charged automatically. The guest must complete the payment to receive their stay extension or incidentals.” It adds, “If the guest does not pay, the request expires after three days.” Do not describe the fee as automatically recalculating an existing stay.
Once payment has fully settled and the guest has checked in, edit the guest count. Vrbo states, “You can update dates, number of guests, and whether the group is traveling with a pet after the guest has checked in.” The Vrbo Owner Dashboard guide gives the broader dashboard context, while Airbnb vs. Vrbo for hosts explains why the two workflows should stay separate.
For one reservation, keep the approved number of guests distinct from the maximum number allowed. Occupancy rate is the share of available nights sold during a period. A home can have a maximum of 4 guests and sell 21 of 30 available nights, which is a 70% occupancy rate: 21 ÷ 30 × 100 = 70%. The 4-person limit and the 70% booking metric do not measure the same thing. For the booking metric, see what a good Airbnb occupancy rate means.
I keep these messages factual, short, and tied to the reservation record. Replace the example numbers only after checking the actual booking and maximum.
None of these messages promises enforcement or labels the charge a penalty. If you need examples for other stages of the stay, see these Airbnb check-in and checkout message templates.
BnBGenius can answer guest messages on Airbnb and Vrbo 24/7, so it can keep headcount questions and your stated rules consistent. Say a guest asks at 11:40 PM whether a 4th person can join a 3-guest booking: the communication can be handled promptly, while the decision stays with the host. That division is the useful one—routine communication can be delegated without delegating control.
BnBGenius handles routine messages and escalates money or extra-guest decisions instead of guessing. The host makes those decisions. See how the communication layer works in Airbnb automated messages and Vrbo automated messages; the wider division between automation and host decisions is in how to automate Airbnb.
