We stayed only one night, but we had what we needed: proximity to Universal studios, someone to help us out planning the day at the park, many food options, comfortable bed, soft towels and a lot of space to lay out our suitcases (this stay was a part of a bigger trip). We even had a room with the view of Hogwarts! Also, the rooftop restaurant is great, good food and nice sunset!
It was very convenient because we walked from the hotel to the park. In the morning, this is extremelly useful because the security gate is much closer to the ticketing gate, compared to the shuttle bus station. Plus, we had early entrance as guests of the hotel.
