I am going on the 12 night Mediterranean cruise in May and I noticed that many of the ports are not in the destination city (including Rome, Athens, and Ephesus for example).  The Royal Caribbean website only says there is a nominal fee charged for a courtesy shuttle to and from the port and destination city, but I cannot find an example of the cost anywhere?  Has anyone done the Mediterrean cruise?  Do you remember about how much it cost for the shuttle?  I know it will probably vary from port
