I can confirm the fix works. Thank you!
The option is checked for me too, and either way on the new booking that keeps failing there aren’t conflicts on the first/last day.
I can confirm this issue on both 1.7.1.1 and 1.7.1.2. I’ve set up 5 rooms, small hotel mode disabled, no optional parameters at all (just a comma separated list of room names), and I keep getting “Checkin or Checkout overlaps another booking” when trying to add a booking from the admin interface.
I already have other bookings in the database for the same 5 rooms, made with previous versions of the plugin with no issue.
If there’s any further information I can provide to help fix this please let me know.
