Eric that is true, we went ahead and booked an aft mini suite on the Jewel for a repo next fall from NYC. it is a similar itinerary in reverse to what we did this spring on the Spirit, but we will have the benefit of a much nicer cabin and the newer ship.
For an "older" ship the Spirit actually handles freestyle very well. It does lack space sometimes for the entertainment it offers. the bars are pretty small and they'll stick some guy playing keyboard in a small area and it just doesn't work too well. We had a meet and greet in Henry's Pub and our group was spilling out into the Atrium, because there wasn't nearly enough room. But as usual, the good outweighs the bad and I am sure you'll have a great time no matter what you decide.
