Was in Tortola last week on the Zuiderdam. It was a great cruise and a great time Tortola. We were in port very early in the Morning ( by 7am ) got off boat by 8am. Had to be back to boat by 4:30pm. Ship sailed at 5pm sharp.
Went by cab to Brewers Bay for the day. It is a beautiful and quiet beach but has a beach bar. Glad to answer any question you might have.
