there is just the 2 of us, but here is what we do when we drie down and get there early.
we stay at a motel in Kissimmee (but youcould stay at celebration or lots of places.)
the Rodeway Inn has a nice pool. not disney, but nice. 2 nights. you can eat at a Ponderosa or one of the many buffets.
there are tons of mini golfs and shops. tons of fast food places. or do a show (medievel times, etc)
we walked to Old Towne. there are rides, shops, places to eat or get a cocktail, go carts, etc.
spend the day by the pool. you really only have one day to kill (and you can still drive over to downtown disney and use the planet hollywood voucher, walk around, etc).
after the 2nd night, get up really early, and check in to POR at 8 am. even if your room is not ready, you're at DISNEY! eat breakfast at the food court. etc etc. (get a jump on anyone else as far as room requests go)
