The Adult Sanctuary Cabana's are located in a roped-off area, and there is (usually) someone standing at the rope to let people in (or turn them away if they haven't rented one). But toward end of the day, that person disappeared. It wasn't really an issue, as many people had already returned to the ship. We did have someone ask us several times if we wanted anything to drink, but the bar was located fairly close to the cabanas and it was just as easy to get our own. We got our own food - I think I remember that you can purchase additional food that would be delivered to the cabana. You cannot enter the beach from the adult area, as there are rocks there. One note - behind the cabanas is a dirt road that people can walk down if they choose. So the adult cabanas aren't really private. But it was nice to have a place to keep our things, and have air conditioning since it was pretty hot. There is a outdoor shower that we used to cool off also. All the cabanas may have them though.
