The Tahiti building is best(used to be called the Moorea building) it is the closet building to the TTC and has the BEST views of the Castle.If you stay on the ground floor lagoon view you will be able to feed the ducks and other birds that will come right up to your room.If you stay on the top floor you get a better view of the fireworks and you can actually hear the Wolf sound effect from the haunted mansion as well as the MK train whistle at night which I thought was pretty neat.
