I don't find the pools themselves being overcrowded, except ones that allow kids
. It is the area around the pools that are crowded, especially the pool were the band is playing or there are activies. If I cannot find a lounge chair on the pool deck, I usually can on the deck above overlooking the pool.
One of the 1st things I do on a ship is look for a pool that restricts kids and will frequent that pool doing the cruise.
