When we go in November we got these 3 park unlimited tickets which are good for unlimited use during a 14 day period starting the first day you use it. We are only there for 7 days but it was cheaper than buying 7 days worth of tickets. Undoubtedly this cost more than an Annual Pass. Could we go to the window and upgrade on day 1? They should give us a refund, lol! I know that won't happen but could we upgrade those tickets and not pay anything? I'd probably upgrade on the last day to be safe and not get blocked out of anything, we already have free Express because of the hotel.
