I read another article a few weeks ago about the damage being caused by all these big cruise ships and the wakes they make. Even though the ships go slow when arriving and leaving port, the concern was about the constant big waves hitting the buildings.
But I hear what you're saying about the crowds. When we were first there, it definitely didn't seem as crowded as the last time. I'd have to go back and look at my pictures, but if I remember right, there were about 8 ships in port one day we were there. That's about 20,000 - 25,000 people and they all want to go to the same places making them unbelievably crowded.
It's such a beautiful, wonderful, and magical place. I do hope they put some limits on the number of ships that can visit each day as I would hate for it to lose what makes it so very special.
