On Day 4, we would be docking in St. Thomas. We weren't scheduled to arrive in port until 11 AM, so I had plenty of time that morning to wander the ship and take photos.
It was early, so the pool deck was empty.... but also it was a port day. If you're not interested in getting off at a port, port days are a great opportunity to stay on the ship and enjoy the pool with less guests onboard.
