You can ask for a specific building, but they will say they can't guarantee it. I requested Congress Park, and that is exactly where we stayed. I just called to confirm the week before and they said to mention it at check-in to remind the CM's. Now, there are two main areas that I would recommend staying in. One is Congress Park. The major perk to staying there is the path to walk to DTD is right behind the buildings. You can walk the path (roughly five minutes to the DTD gates) or you can hop on the bus. You also have a great view of DTD and Pleasure Island being right on the lagoon. The perks of The Springs is that it is centrally located across from the main pool area, the Turf Club restaurant, the food court, and the gift shop. If you have small children, you may want to stay there mostly for easy access to the main pool. Either way, enjoy!
