Grandparents with two grandsons 16 and 12 Ertunga picked us up at port and we were in advance of the boat tours so we even had Mary’s House all to ourselves for a few minutes. ( special) Ertunga did an excellent job of talking about history with the boys. We saw a lot and had just us 4 with a guide. At the end of a safe day Ertunga returned us to the ship. Great 5 star tour.
