A friend of mine stayed there about 2 years ago and at the time they did not have microwaves in the room. Also he tells me they did not have refridgerators either, but they did have coffee makers. I stayed there about 6 years ago..
The hotel is rather spread out. The Hyatt Orlando consists of four clusters of 2 story buildings all with internal corridors. In terms of room requests, it depends on what you are looking for. You may want to reguest a room that looks into the courtyard, as opposed to the parking lot. I beleive that they have pools at each cluster of buildings. Also this hotel borders on I-4 so if you don't have an room over looking the courtyard, you could look past the parking lot onto a freeway. Also, if you don't have a car you may want to request a building close to the main lobby building, if you want the shortest walk to the busses, dining, etc. One other thing, depending on your needs you may want a ground or 2nd floor room. Ground floor rooms have patios and of course the 2nd floor rooms have balconies, so it depends on your preference.
