Saw your profile on TravelChums. I have to say, I love Princess - while the cruise line 's pricing policy is not particularly sensitive to single travelers, I have always met wonderful people and other solo travelers. My favorite memories are the champagne toasts with new friends at sailaway. If departing Italy, wonderful Italian music is playing. If in France it's Edith Piaf.. It's so lovely there...not to mention the ship's aft outdoorJacuzzis at sunset...
I realize the Royal Caribbean cruise you are interested in has a few more ports in the Mediterranean. That may be more important to you. However, if you think you might find the Princess cruise intriguing, please write to me directly at my email address.
