I cruised solo this past June, and let me tell you it was wonderful! In fact for the first time in many years, I was able to unwind and not worry if everyone was having a good time, or planning activities that the whole family would enjoy.
I went on a four day, and right off the bat I met another person who was cruising by herself, and we had got a long so well that we immediately had our dinner seatings arranged.
It really was so much fun, that i now have another cruise in January 05 booked that i will be going solo again.
