Great ship, great fun, great food, great ports of call. While Barcelona, Athens, and Alexandria were exciting, we found the smaller ports of call more to our liking - Rhodes, Villefrance, and Messina.
Number one suggestion is to avoid the ship shore excursions -- too pricey, you can do better on your own. In Turkey and Egypt, be sure to make it clear you do not want to be taken to carpet, ceramic, leather or papyrus making places. They are the foreign equivalent of car dealerships - "What's it going to take to get you on a carpet today!?"
RCL could do a much better job of connecting to the culture of the ports of call in their menus beforehand a la Italian dishes, when calling Italian ports, Greek selections, when in Greece etc.
A truly great benefit of both the Transatlantic and Med cruises were the enhancement talks about Digital Photography from Sandra Ettlinger. Wow, what a difference in the photos we and our friends ended up with. Check her out at Ettlingerproductions.com
