We were at that night launch as well, (Hi goofy!).
The Captian and crew kept up with the shuttle schedule and made sure we were able to see it. They also showed the launch and countdown on the big screen on deck.
We were in the middle of dinner during the launch and the servers kept us up to date on the timing. Just before the main course we all, and I mean the whole restaurant, went out on deck 4 to watch. Behind us I heard a server saying to another. "Should we be out here? Our job is inside" The other server answered. "All our guests are here and we are serving them here."
I seconded that.
We missed the "Show" for AP but it was so worth it.
I crossed one thing off my "Bucket List".
Have fun and good luck.
