Similar to the cutoff time for activities, this setting lets you define when guests can no longer book a package that includes accommodation. To set it up, go to Sales > Booking Engine > Booking settings.
For example, if the cutoff is 2 days before check-in at 17:00, users won't be able to book the package after that time.
If you set it to 0 days before, guests can book accommodation on the same day, up until the cutoff time.
