As an update, the Pearl did dock at Taino Bay on Jan 25. Much like other built up ports, we had to walk quite a distance in order to exit the port area and meet our independent excursion. At one point, you have to walk through a store to continue on, which was even more shady, imo. They appear to be building a lazy river to go along with the pool that is already open.
Low tide that day was at 6pm, which was the time we were scheduled to leave. We ended up leaving around 7pm, but since I was on a music cruise, I now have some amazing photos and video of the shows with the island in the background.
