It would be wonderful to have the option for a patron to have the option to purchase an "add-on" ticket once it is confirmed they have purchased an original ticket type. Think--buy this program plus materials kit and get a second materials kit for a lower price. This would prevent users from taking advantage of the system and just purchasing the lower price type.

Yes! also, make certain tickets only be available with the purchase of another ticket Example - you can only purchase a free planetarium ticket with the purchase of general admission (or exclusivly after a timed entry ticket in the era of Covid)
