Deck 5 seems the best space to curl up with a kindle or play a game of Phase 10. When I go looking for Linda, here is where I start, or outside on the port side of the promenade deck. Fresh from several hours of writing, I relax my mind by watching the passing ocean, or playing the daily sudoku, which isn't much of a challenge.

I suspect the tiled area is meant to be a small dance floor, but I have never seen it used as such. There are more private niches if you seek them out.
