Set the entry times with their capacity, close days or time slots, and adjust the capacity for a specific date.
Time slots are the entry times guests choose in the widget, each with a capacity: how many people can enter at that time. Skyrez subtracts the tickets sold and stops selling when it's full.
First you need your attraction with its ticket categories. See Create your attraction and its ticket categories.
On your attraction page, open the Time slots tab and click Add time slot. Fill in:
Save it and repeat for each entry time. Time slots apply every day.

Each ticket counts as one person: if a family buys 2 General and 2 Child tickets, they take 4 spots. In the widget, each time shows as Available or Sold out. If someone tries to buy more tickets than are left, the widget tells them how many spots remain.
In the Closures & capacity tab, click Add closure or capacity adjustment and fill in:
Click Add.

To remove a closure or an adjustment, delete it from the list. If you close a date that already has tickets sold, those tickets are not cancelled automatically: check them in Bookings.
