They moved to a central hall, took the elevator, and reached the top floor first.
This is the smallest area up here, but the open-air swimming pool in the middle is no smaller than the pools in regular swimming centers, with its clear light blue water rippling, enticing one to jump in for a swim at the sight of it.
The pool is equipped with a heating system, so although it's a bit chilly now, going in the water isn't a problem. However, since the cruise just began, no one is swimming here yet. Still, people occasionally take the elevator up for sightseeing; the highest point of the cruise is everyone's first choice as it offers a spectacular view. Moreover, the habit is to explore each level from top to bottom.
Apart from the pool in the middle, there are also plenty of beach chairs around for guests to relax, and a small bar nearby serving various drinks and snacks.
