Of the seven ports we visited, Kotor in Montenegro proved to very scenic, particularly the two hour duration en route to the harbor. It reminds us of the fjords in Norway and the highway going up Whistler in Vancouver, British Columbia.
Split, Croatia is very special too. We took a coach to Trogir, a UNESCO town. Very well preserved and relaxing.
Santorini is magnificent. We took a bus and spent most of the day at Oia, the poster perfect town that can consume your entire camera memory card and spare batteries.
Venice is full of tourist and the best way is to avoid the crowd by wandering around the other islands after you have checked out St Mark's square.
Athens has a lot of history and since we were there not too long ago, we decided to take the subway to town and wandered around the foot of the Acropolis.
We subsequently complained to the general manager of Ephesus Deluxe upon return home and received a 50% refund. It was not about the money because we thought we were dealing with a tour operator who would assign tour guides with proven track record of high quality customer service. This was certainly not the case.
