From the Turquesa, you are going to be taking a cab to any other hotel, as it is off on it's own.
There is a day use fee, for the hotels, but it varies in price, depending on which hotel.
If you are just looking for a tour, I would suggest asking at the reception desk, and tell them that you are checking it out for a future vacation plan, and I'm sure they will arrange a walk thru.
