Pro users:
When linking a listing to Booking.com, you choose which Guesty rate plan(s) or cancellation policy to apply to the listing, and they will be used instead of the rate plan(s) you set on Booking.com. The latter will be deactivated during the linking process.
Avoid creating rate plans in Booking.com for your connected listing, as it may cause syncing issues.
Lite users:
You need to set one rate plan on Booking.com before linking your listing. When linking it, Guesty will deactivate your Booking.com rate plan, and use your Guesty cancellation policy instead.
