I agree with the others -- very nice hotel, but definitely geared toward convention/business travelers. Their self-parking lot was way at the back of the hotel and it was about a 1/2 mile walk through the building to get to the elevators to get to the room. Very hard to do with three small children after a long day at the theme parks. Also, my kids seemed to attract so much attention when they were just being kids, goofing off at the pool, ring around the rosy in the lobby, etc. Of course, I may be biased, but I don't think my kids behaved badly, they were just being kids. We tried to keep them out of everyone's way but it seemed like we were always stepping on someone's toes. The "business" people at the hotel seemed too stuffy for us. We got the room on Priceline for $42/night but have been gun-shy about bidding the Universal area for a 3* because we might get the Rosen again. Of course, if you're traveling without kids, you may prefer the Rosen. Have a great trip whatever you decide.
ETA: forgot to mention, the self-parking lot was free when we were there, just very far away!
