What are some good hotels to stay at in Orlando?

I’m going to Orlando sometime in May with my girlfriend. We’ll be in Florida for a week (give or take a day), and in Orlando for probably 5–6 days. Ideally, we would want 2–3 days to go check out a couple of the Disney Parks, Sea World, and possibly Universal or other attractions. The rest of the time we’d like to spend lounging about, and probably hitting up some night life in the evenings. I’ve been to Orlando many times, but my father lives there so I’ve never had to venture out and find a hotel. Does anyone have any recommendations?

I’ve been looking at the various Disney resorts themselves, and a few of their moderately priced themed ones look good. Extra points if you find/know of a hotel that we can reserve with included park entry or other extras (though airfare will likely not be an issue as we plan on driving ourselves as of now).

Thanks for the help!
