For U.S. Military and Retiree's, get a room at The Shades of Green AFRC Hotel, on the Grounds at Disney Orlando. Buy your passes there (4-day Park Hopper for $154 -- you don't pay tax at the hotel -- you will at MWR or at the gate). Park fee for each day at the hotel is $5 (in the garage). Bus departs for the various parks every 20 minutes from the Hotel, and certain days you get "Magic Hour" where you get in an hour early (rides aren't open, but you get into the park before the crowds and get to the rides just as they open). So, you get in the park at basically $40 per day, all day, and multiple parks....can't beat it if you have to make the "Haj" to the Mouse.
Hotel is excellent, two restaurants offer the best food for the money (the Italian restaurant is my family's favorite), there are multiple pools and a spa as well as a sports bar. There's also a PX/BX in the facility, laundry rooms, a Starbucks, a regular grill, and lots of other things...
I live about an hour away, and when I must make the "Haj", I spend the night at the hotel....far less stress and parking for two days in the regular spots WILL PAY for the hotel room.
