Hi!
In 2000 we took the Navigator from Seward to Vancouver in early July. One day( I believe it was in Ketchikan) it was in the low 70's and we decided to use the pool. To our surprise it was a heated pool so it was great! My friend and I were the only ones in the pool! I don't know if the Mariner pool is also heated but I would bring the bathing suit just in case!
