We were looking for something to do before boarding our cruise ship and this seemed to fit the bill. We had dropped off our luggage and headed up the hill toward the fort. We've been to several tours of this type and always look forward to the uniqueness of each fort. We didn't have a guide but there are adequate signs to explain the purpose of each room and displays to show how the residents dressed and lived. A convenient souvenir shop with air conditioning was a great find after walking down a long tunnel. We were able to see our cruise ship awaiting us so we only spent about an hour hear but you could easily spend a lot more time investigating all the nooks and crannies and great photo opportunity locations.
