The new MSC Seaside is scheduled to launch in December of 2017. The ship sail regularly from Miami, beginning December 23, 2017.
Take a look at the ship preview video released by MSC (at bottom of post).
Features of the new MSC Seaside include a nice, wide promenade deck that goes all the way around the ship and provides spots for dining and shopping; aft elevators with panoramic views; a kids-only restaurant; and an aquapark with slides that extend out over the sides of the ship (yikes!).
The Seaside was built to cruise to warm Caribbean destinations and that’s evident in the ship’s design, which emphasizes use of outdoor spaces.
