I just stayed at the Renissance Orlando Marriott across from Seaworld last week.
It is beautiful! The rooms are very nice, spacious, we requested a balcony and got that too. The pool setting is wonderful, very relaxing, yet fun for kids. Nice pool Bar. Right smack dab across from Seaworld. I got this resort for $99 from Priceline, so I just ended up there and loved it. I did check the Tripple A rates and they were around that price too. I probably could of got a cheaper rate through priceline but I was bidding high in hopes to get Hardrock Hotel.
Anyway I was very pleased with this resort. Have fun!
