We just returned from our stay at the Hilton Suites...there is a reason why they are quoting you great rates! They are one of the furthest hotels away from the parks. You have to use the ART system if you don't have your own vehicle and the service is horrible. Also, the hotel is in disrepair.
When we were there, of the two elevators they had only one was working and the door would not open on the 3rd floor...you had to go up to the 4th floor and walk down the stairs. And of course, because we were a late arrival we were assigned a Smoking room and the 3rd floor! The room looked like it hadn't been used in a while and was very shabby looking. The security chain on the door was broken off. They moved us to a Non-smoking room on the 10th floor the next day, but it wasn't much better. All the light fixtures were practically falling off the walls. The furniture was in need of replacement and the air conditioner wasn't working. The outdoor pool was drained when we first got there but was operational by the time we left four days later.
The hotel itself is very isolated and there are no restaurants nearby except the one in the lobby which is very overpriced and a Del Taco down the street.
This is more like a Motel 6 than a Hilton. Pay the extra money to stay closer to the parks (preferably at a hotel that has their own shuttle or within walking distance). Your trip will be much more enjoyable!
