# Booking rules (/en/businesses/reservations/booking-rules)

Booking rules apply to customers booking resources in the Thril app and on the web, and each venue sets its own. Classes and events have their own [registration rules](/businesses/events/registration-and-payments), a course chooses the [refund when a participant leaves](/businesses/courses/payments#refunds-when-a-participant-leaves), and [services](/businesses/services) set their own cancellation deadline.

## Keep prime time fair and cancellations in check [#keep-prime-time-fair-and-cancellations-in-check]

- **Fair access to prime time.** A 14-day **Reservation window** and at most 3 future bookings per customer keep a few regulars from taking every evening. Members can get a longer window with a [membership benefit](/businesses/shop/memberships/benefits#booking-earlier) or a higher limit with a [reservation restriction](/businesses/shop/memberships/restrictions).
- **Strict cancellations without empty time.** A 24-hour **Reservation cancellation deadline**. After it, customers put the booking up for sale, and someone else can take the time.
- **Season slots that stay booked.** With **Disable cancellation of recurring reservations**, a club that can't use its weekly slot puts that week up for sale.
- **Walk-up booking on the web.** With **Allow anonymous reservations**, a first-time customer books without signing in.

## Who can book and how far ahead [#who-can-book-and-how-far-ahead]

- **Enable resource reservations** turns customer booking on or off for the whole venue. Staff bookings and recurring reservations for sale in your shop work either way.
- **Allow anonymous reservations** lets customers book on the Thril web without signing in. They enter their contact and billing details at checkout. The app always uses a signed-in customer.
- **Default booking view in the Thril app** shows your free times as a list or as a calendar of resources.
- **Reservation window** is how many days ahead customers can book.
- **Max simultaneous future reservations per user** caps how many upcoming bookings one customer can hold. Bookings the customer made and open games they host count. Leave it empty for no cap.
- **Reservation instructions** go in the confirmation email and stay in the app for confirmed participants. Door codes, parking and house rules fit here. Each resource can have its own instructions too.

A membership with a reservation restriction can replace the cap for its members. A venue cap of 3 with a membership allowing 5 gives members 5 and everyone else 3. Read more in [Reservation and event restrictions](/businesses/shop/memberships/restrictions).

A shorter window or a lower cap applies to new bookings, and customers keep the ones they hold.

## Cancellations and resale [#cancellations-and-resale]

**Reservation cancellation deadline** is how close to the start customers can still cancel. Each resource can have its own deadline or turn customer cancellation off. Read more in [Resources](/businesses/reservations/resources). A new deadline applies to every upcoming booking from the moment you save.

Before the deadline, a customer who cancels gets their payment back. After it, the customer can put the booking up for sale, and staff can still cancel and choose how to refund. [Managing reservations](/businesses/reservations/managing-reservations#owner-sale-and-cancellation) covers what happens when a booking sells and how the money comes back.

**Disable cancellation of recurring reservations** keeps customers from cancelling reservations that are part of a series. They can put them up for sale, and staff can cancel them from the dashboard.

## Participants and payments [#participants-and-payments]

- **Allow inviting other users to join a reservation** lets the booker invite friends as non-paying participants.
- **Allow sharing reservation payments with other users** lets the booker split the price so each player pays their own share in the app.
- **Payment disclaimer** shows on the checkout page before the customer pays, for terms customers must see first.

Staff can add participants and set up a shared payment on any reservation, whatever these switches say. On a resource [priced per participant](/businesses/reservations/resources#pricing-per-booking-or-per-participant), every player pays their own price.
