Rhodes would probably easy make it into the top 25 visited list on a community site for package tour travellers. The city is stuffed with visitors from cruise ships and the nearby party destinations, like Faliraki. No need to mention that almost every building within the walls is either a restaurant, a shop or a pension. Nevertheless Rhodes is one of the most beautiful medieval cities I've seen so far. The 4km town wall is stunning. The city is set at the sea and was occupied by the Ottomans for a few centuries, creating a really special flair. Further, Rhodes island is one of the sunniest places in Europe. Chances that clouds are ruining your pictures between April and October are pretty low. Definitely worth a trip.
