I do have to add that buying the discounted tickets ended up being a pain, but I think it saved us around $50. I visited guest services at USF and had to wait (they only had two people working), then they rang me up and I tried to use my room charge. Well, they have a new system and room charge doesn't work, but it seemed like it did, so the whole transaction had to be voided (supervisor had to come over). Then we had to do the transaction over again with my credit card.
Anyhow, between express pass and the dessert party, the only things we ever waited for were paying for things (guest services, food, hotel bill with gift cards was a PAIN)
