We like the DoubleTree Guest Suites in DTD. You can walk to DTD they have a large pool, childrens pool, jacuzzi, bar area, arcade, movie area w/kids movies. I like that we can put the kids to bed, shut the door and watch TV or what ever! We were very happy with our accomodations.
We have also stayed at the Caribe Royale. Another GREAT suite hotel. Themed pools w/water slide. Loved it!!!! However, for the price and the additional drive to the parks and not being so close to DTD I probably wouldn't stay there again unless the DoubleTree was booked. It's just so convenient there!
