Wow -- $35 is steep. The fitness room at the Westin hotel is nice -- it overlooks the pool above the restaurant.
I think they had to do away with the shared-pools because people from the Sheraton were all coming down to the Westin pool, which is nicer and a short walk. But the Sheraton has a nicer beach -- one nice feature of stay and play is that you can reserve the cabana/covered chairs on the Sheraton beach and pay with your room key even if staying at the other two. I wonder if they've done away with that. That would be a shame. They are a great deal for the day.
