If you or your customers are unable to increase the ticket quantity during checkout, preventing additional tickets from being added to the booking, the likely cause is your booking restriction settings.

For example, let's say a theater teacher at the local high school is trying to book opera tickets for all 30 of her students at once, plus herself. Although we’ve Set Our Activity Capacity Limits to accommodate this, she’s unable to add the full 30 tickets to the cart at checkout, as shown below. This indicates that the activity is tied to a booking restriction allowing a maximum of 25 tickets per transaction, which is the default booking restriction setting.

To correct this:

1. Make sure you have Set Activity Capacity Limits‍ to the desired settings for the activity.
2. Confirm the issue is being caused by the booking restriction associated with the activity:
   1. From within the activity, select Restrictions from the sidebar menu
   2. Take note of which restriction appears in the Choose a Restriction drop-down menu, then follow the Setup Restriction Policies link and select that same restriction from the list

4. Confirm that the maximum(s) listed under the "only allow new bookings" fields match the cutoff number you are experiencing during checkout

5. Before you making any changes to this restriction, scroll down to the Uses section to review all activities associated with it

6. If the changes you wish to make to this restriction will not negatively impact any other activities associated with it, simply make your desired changes and choose the Save button. Otherwise, you will need to Create a New Booking Restriction and Assign the Booking Restriction to Your Activity.
