We stayed there last January and were hoping to repeat it this January, but the rate is double what we paid last year.
We stayed with 2 adults and 3 teens for almost a week. We had plenty of breathing room and two tv's. Fridge & Micro. They brought us another chair since the table only sat 4. We had the cold breakfast buffet every morning and it was excellent, lots of fresh fruit and a variety of breads, muffins, cereals, yougurt.... Pool is average and alittle loud with the highway behind it but wasn't really swimming time of year so that was okay. Maybe in a busier season it would be more "hopping" out there and we wouldn't have noticed. Ask for a room facing Downtown Disney (as opposed to pool view). We could see fireworks. Service was excellent. Rooms were recently renovated and the beds were the awesome Hilton beds. Lots of space for clothes as well.
You don't have to have a car.........but I would. It is the longest walk on the blvd to Downtown Disney. Girls may enjoy the shopping and hanging out there in off time. It will be worth it rather than tie yourself to transportation system.
