I agree that the World Cruise can be something special...it was for us!
I also agree that if I was to do only a segment, it probably wouldn't be the last. For by that time the World Cruisers are trying to wrap up final dinners and activities with many of the friends they have made over the past 100+ days...and may not be as gregarious toward newcomers as we found almost everyone to be at the beginning of the trip.
I have to agree, Jamie and Dana are two of the most solid people one could ever hope to meet. They are caring and sincere...and know what's important in life.
