If you are from Alaska, yes it is heated and nice. If you are from warmer regions, then no. Seriously. I couldn't believe the number of people in the pool in December on a cool afternoon. The issue isn't so much the water temperature, it is the air temperature and the wind off the Pacific Ocean. Gettig from the pool to your hotel room is the part where you will freeze. The Neverland pool is in a wind tunnel between two towers. The Bonita pool is sheltered from the wind.
It is all relative.
