Oh one other thing,
we enjoy yacht watching in a lot of these ports, especially Monacco and Mallorca. There was one in particular called Lady Moura that caught our eye as it was extremely impressive and it seemed to be following us as it showed up in three of the ports we were in during our cruise. We like to take down their names and look them up when we get home. See who owns them and all the details.
We found out when we returned that Lady Maura is the 11th largest yacht in the world. She even has a helicopter on board. Here's some pictures of her we found online. Kind of a neat way of continuing the enjoyment of your cruise even when it's over.
