We have done quite a few cruises on various lines, this was certainly the "newest" ship we have been on.
We flew from Austin-DFW-Miami at dark thirty, arriving Miami just before noon, a quick taxi ride to the ship. On the ship in 10 minutes. Easy.
We booked an outside cabin on deck 3 since it was a short cruise. It was convenient to dining, music, entertainment, etc. Very nice room, seemed bigger, so did the L-shape bathroom with glass shower doors- even the shower seemed bigger!
3131-port side, quiet, half way between theater and reception.
