Got through to support another way. It looks like each of my annual passes for Busch Gardens can pull 3 guest tickets each per calendar date.

In other words, I can get 6 tickets at 50% off. We could either split that discount up among the whole group evenly, raffle it, or make it first-come, first served.

If we decide to pick another activity instead, I can look into ticket discounts for locals and we can do something similar.
