Will be taking the galaxy on August 2nd. What should we do in Rhodes, tour or walk the old town on our own? In Katakolan, is Olympia a must? Also, what beaches should we go to on Mykonos and santorini? Dubrovnik we plan to just walk around on our own. We like to have lunch out so we can sample the local cuisine. Any suggestions for all of these places? The ship says that there is limited taxi service into taormina. Are we going to have a problem getting there?
