My trip will begin on Sept 10 and end on Sept 18. We are planning Discovery Cove on Sunday Sept 11, Busch Gardens on Monday, Aquatica briefly on Tuesday, then a nap and Mickey's Halloween Party, US/IOA on Wednesday, Thursday, and Friday, and finally Sea World on Saturday and back home on the 18. My question is, I am just wanting to book the DC with a hotel room this week and just buy the tickets for US/IOA and not do the packages or stay on site. How much am I missing by not being able to do the early entry?
