I would like the ability to set a date and time for which a purchaser can purchase a pass. I would also like to set a time when the pass is no longer available for purchase. For example I would like to be able to sell an Early Bird pass from 12:01am on Dec 1 until 11:59pm on Dec 22. I would then like to be able to sell Full Festival passes starting at 12:01am on Dec 23 until Jan 15. We plan to only sell passes and then have the system generate the appropriate tickets when the pass is scanned. We have a 3 night in person festival. We will scan the pass once each night and then the nightly ticket will be generated. We don't plan to sell any tickets.
