It's all about the hammocks!!!
If it's about Serenity Beach and hammocks,well,there are only about 3 hammocks and there are always a few people playing what I call, roller derby,elbowing each other,trying to be the first off the ship to get those hammocks.
There are more hammocks at the family beach,but they are definitely the desired real estate and they are the only thing I hear/see people stress over.
If hammocks aren't that important to you,then you will be fine,finding seats/umbrellas just where you'll want to be.If hammocks are something you'd at least want a shot at trying to have,then you do need to get off asap.That's always been what I've personally witnessed. Someone on another thread wrote about finding a few hammocks by,is it Gils Fins Shack(?). It's apparently an area farther from the water and no one expects hammocks to be there. Just something I read........
But there are plenty of chairs/lounges/umbrellas wherever you'll want to be.
The less you stress over CC, the more time for fun!!!!!
