Avoid double bookings with a hard lock
Two families want the same week? CasaCal won't allow it, because the lock lives in the database.
Start free for 30 daysRefused by the database
A hard constraint at the database level refuses two overlapping stays outright. Overlaps are technically impossible, not just unlikely.
Accurate to the half day
Departure counts in the morning, arrival in the afternoon. Both fit on the same changeover day without ever counting as an overlap.
The calendar shows what's free
Before anyone logs a stay, they see the current state. Nobody has to check in a chat first.
The same rule for every booking
The lock treats owners and members the same: whoever logs a taken half day second gets rejected.
