The standard concierge rooms that have a castle view are on the 3rd and 4th floor. We stayed in room 4404 on one of our trips and the view was incredible. I also liked it because there was no one above us. That wing of the resort only goes to the 4th floor. It's a bit of a walk though to the concierge lounge and the main elevators, but that made for very little hallway noise. There's a back elevator there that brings you down to an alcove located next to Gasparilla's Grille.
Put in a request with your concierge pre-planner, but as Renee mentioned, list your requests by priority.
