Yes, my partner and I will be going on the Rhapsody on March 21st. I just did that same cruise by myself a few weeks ago (as I needed a break) and really loved it so my partner and I have booked an Owner's Suite and will be going again in March.
Will you be sailing by yourself? If so, I had a really great time traveling by myself and you won't have any trouble meeting people.
p.s. Where are you from?
