One time my fiance and I went to Orlando and went to the Welcome Center to find a hotel to stay at for two nights. They hooked us up! The Rosen Center, located across from the Convention Center, is a really nice hotel that's usually outside our comfortable price range and we were able to stay there for $59 a night.
It has an executive fitness room (for a fee), I think a sauna, a really large pool and the coolest hot tub I've seen -- it has a waterfall!
Very attentive bell staff and concierge, HUGE lobby, gated parking for guests only, and walking distance to restaurants. All in all, it's a beautiful hotel and I wouldn't mind staying here every time I visit Orlando.
