In your Business Settings app, head to the Memberships tab and select any existing membership or choose to create a new one.
When you start filling out the details of the membership you will get to "Membership Scope." Here you can choose limited access days and times
If you tick limited access, then all days of the week appear. You can click on the plus sign and enter the limited access times.
You can use, for example an off-peak season ticket, only between 9.00 in the morning and 17:00 in the afternoon. Or add a membership you only can use in the weekends. You can offer these memberships with discounts, to spread the crowd throughout the week an day.
