We went on Royal Caribbean's 7 night Eastern Mediterranean cruise leaving out of Civitavecchia and stopping in Sicily, Athens, Turkey and Crete.
I was impressed with the efficiency of the check in process which went very fast. I believe we were in our room in about 30 minutes after arrival. I wasn't crazy about having to hand in my passport (only applicable for non-EU passport holders) but the passports were returned quite promptly on the last night of the cruise without any problem.
We had an interior stateroom on deck 7. Our room was fine. Nothing spectacular, but it was clean and the bed was comfortable enough which was good. The bathroom is small, but functional. No clocks in the room, so bring a travel clock if you feel you need one.
Decent room. Older TV, no clock. Clean with comfortable bed. Adequate and ample space for the lowest cost room.
