We'll be arriving at the Dolphin mid morning. Check in isn't until later in the afternoon, but we'll be sure to stop by the desk at arrival. Since we won't have a room in the morning to put on our bathing suits, is there a changing room near the pool? As Starwood Gold members we can request a free late check out, so this won't be a problem on our last day, but pool time is an important part of our vacations.
