Actually, there are 4 different areas that make up the Tortuga club portion of the resort per say.
There are 5 3 story buildings surrounding the Premiere pool which has a Bar in the pool, music during the day and several activities like bingo and name that tune daily. So, a bit noisy for some to be there.
Then there are three 3 story buildings surrounding the quiet pool. There are no children allowed in that pool and its very quiet. So good for some that don't want any noise disturbing their nap.
Then there is one 3 story wood building, ocean front at the extreme north end of the property.
Next door to that is the Seaside building on the beach, that has two more stories than all the other Tortuga buildings and is the only one with an elevator.
If you are trading in from RCI then you will get either a pool side unit or a ocean front unit depending on where the unit you got from RCI was deposited from. Most RCI deposits are from the poolside buildings.
If you call the resort and request either the premier pool or quiet pool two weeks ahead of time. They will try to accommodate your request.
The Grand and the Londoner are three buildings to the south of the Lobby building which is basically central to the entire resort. The Londoner is actually part of the Tortuga club but is kind of a separate entity within it. all of those buildings have elevators.
All areas of the resort share the same amenities. So, no matter which part of the resort you are in, you can use any of the pools, bars , restaurants, beaches, hot tubs, games etc.
Hope this helps. Enjoy you vacation there.
