Reliability
Overbooking erodes trust and ruins days. Theybook uses a transaction lock so two guests can't claim the last seat, and resource locks so the same vessel, room or guide is never booked twice.
The details
A real transaction lock means the last seat goes to exactly one guest — no race conditions, no awkward refunds.
Assign experiences to a shared boat, room or guide and Theybook blocks any overlapping booking on that resource.
Moving or cancelling a booking respects capacity automatically, freeing seats cleanly and updating the waitlist.
At a glance
Part of your flat monthly plan — no add-on fees, no commission.
