If you purchase a ticket at a table, you are required to purchase dinner. You must arrive by 7pm. There is no minimum for general admission standing room or theater seating, if applicable. There is also no minimum for seating at either The Saban or The Libbey Bowl as these venues have no tables available. General admission tickets are standing room only and have no seats available (this excludes The Saban which is all seating, however GA is open seating and not reserved).
You can upgrade your tickets when you arrive for the show and get dinner seating. You would just pay the difference in price between a GA ticket and a seated one. Upgrades would also be required to arrive by 7pm and you are required to purchase dinner. Availability for upgrades varies depending on the show and what tickets have been sold.
Under 18 must be accompanied by a paying adult. Some events, like Boogie Knights and Throwback Thursdays in Santa Clarita are 21+, but in many cases, it’s Under 18 as long as the minor is accompanied by a paying adult. Likewise, all patrons must have tickets, no matter how young.
If you bought tickets on the dance floor, dinner service ends at 8:30pm so servers are not interrupting the main act.
