When selecting the Tables/Areas that bookings can be placed into in the Areas for this booking type section, Collins will automatically work off the Max (Seated) capacity of the table(s) when placing bookings.
However, you can change this to take the 'Max People' capacity instead. This can be useful, for example, if you offer a Drinks booking type and would like to auto-confirm bookings based on seated+standing capacity. To set this up, go to:
Settings > Venues
Click on the name of the venue
Click on the relevant booking type
Scroll down to "Auto-confirm Rules"
Auto-confirm capacity rules, from the drop-down > choose Standing instead of Seated
Make sure to SAVE the page
From that point on, for any 'Drinks' bookings, Collins will place bookings up to the 'Max People' capacity for that Table, as set up in your Tables/Areas section.
