It will be interesting to see how they bring Back to the Future the Musical to the ship. We saw the touring production (twice) and both nights it had tech issues that paused the show (different cities). The main WOW factor of that musical really is the car and the technical achievements- the original songs over all are lacking IMO but the second half is better than the first half and I really wonder if they are going to be able to pull off the flying car sequence while at sea in its current form. I somehow doubt it.
