Amerisuites does not have a door. There is an open area between the bedroom and living area. Hotelkingdom will probably have something else listed that you will like if you want a separate room.
Hotwire might work for you since they list which hotels are suites, and you can usually find out what hotel it is before you bid on it(betterbidding.com)
Skayauction is an auction for renting unused timeshare property. You have to bid, but you get to see what you are bidding on before you do. Most ready, set, go auctions go for around $60, then you have to add on fees of $210.
I used them for two trips to WDW and once for Wisconsin Dells. It was great 2 have 2 bedrooms, 2 bathrooms(one with a whirlpool tub), 3 tvs, and a full kitchen for less than it would cost to rent a hotel room. There are several people on the boards that have used them(if the search is ever working, you can search and see).
HTH. let me know if you ahve other ?
