Had a stop at Coco Cay on the Mariner on April 26 - the weekend prior to the official opening. We were originally supposed to be the only ship there but Enchantment ended up swapping days in Nassau and pulled in right after we did. I'm guessing they were wanting to test capacity with two ships docked on the same day. We ended up finding spots by the pool and stayed there most of the day. It was fairly empty at first - we were off the ship by 8:30 - but by early afternoon there were no chairs to be found at the pool. Same at Harbor Beach but when we walked around there seemed to be plenty of spots around the outer beach areas.
We had a 3-day on Symphony booked over Memorial Day and just received notice yesterday that they are adding a stop at Coco Cay on Sunday and switching our day in Nassau to Monday. No sea day anymore. From what I can tell we will be there with Mariner so depending on booking there could be upwards of 10,000 passengers on the island this day. Will be interesting to see how crowded it feels - I'm sure now that all the areas are open it may seem less so this time. But I can only imagine the wait for those slides.
I checked out prices for cabanas and things and no thanks - $600 for a pool cabana? With chairs and bottled water? I'm perfectly happy snagging a regular chair and just flagging down a waiter when I need a drink. I'm sure people will pay it though.
Here are some pictures from our visit in April.
