I've never cruised on my own before but would definitely do it again. Started in Rome and left out of Civitavecchia port, next day we were in Scilly (Messina). I had booked a tour through the ship to see Taormina. I found the guide very organized and informative and enjoyed seeing the ancient city, originating in 1440's. Even though I was the only person not "coupled up" I was welcomed and treated friendly by other guests.
After a long day traveling it was a delight to go back to my balcony room all clean and tidy. My cabin steward was an angel, I miss him now I'm home. My room was extra large as the balcony bowed out from the ship I was starboard aft and could see the bridge at the front but also close to the end of the ship. My only complaint about the balcony was my neighbors were heavy smokers and it drifted into my room whenever I opened the balcony.
I choose late dining as we were in port fairly early, the service was top notch and attentive but had a friendly tone. The food was average, none of the meals stood out even on formal nights. I think the RCCL could improve in this area. That being said, the entertainment was wonderful. Second night was a BeeGee's tribute show that had everyone dancing in the isles. I saw the ice show and it was very entertaining, I still don't know how the performers managed such high jumps! In the promenade one evening everyone was dancing to a group of dancers doing the Village People impression. I didn't join in the conga line but maybe I would have if I was drinking. There broadway rendition was also first rate.
The entire atmosphere of the ship was calm and efficient. Another port of call I booked with the ship was the ruins of Ephesus. We left Kusadasi port early and the excursion lasted 5 hours exploring the ancient Roman ruins dating back to the 11th century. A lot of walking on marbled streets filled with chariot ruts but well worth the 3 mile trek. The tour guide had the frailest guest set the pace. Day 4 was Athens which I did on my own but wasn't impressed. Got ripped off for $160 eu for a lunch I didn't order, I only wanted a snack. Wouldn't bother with Athens again. My all time favorite is Chania, Crete. I rented a convertible and drove up around the mountains with the beautiful turquoise waters following me. The only traffic I saw was a few mountain goats. Followed the road along the Northwest coast up to ancient Monasteries, tranquil little villages with the sound of birds calling me further up. I stopped at the British Commonwealth War Cemetary, which lies on a small plateau, just above sea level on the Souda Bay.Along the winding "old road" of Crete I saw many honey farms. The last day out was a sea day, so I took advantage of the saltwater pool on board, it was cold, but refreshing. Overall a great experience. What I would like to see improved would be the food, the spa, the pursers desk (not helpful), and disembarkation process. I was thrown out 3 hours prior to my transfer. Still I would recommend this to any solo travelers or couples.
