Vast spaces dedicated to kids include wading pools, playrooms, teen discos and video arcades. Spas and gyms are huge, boasting dozens of exercise machines and massage rooms. A small ship may have only one restaurant and a bar or two, and maybe a pianist will entertain before dinner. There could be a movie shown afterwards or a crew talent show. There's usually one all-purpose lounge, where passengers can congregate to chat, read, and listen to a presentation about the destination, and a tiny book and video library.
Some small ships have gyms and spas, albeit modest ones.
Conditions permitting, Windjammer allows passengers to dive right off the side of the ship when anchored in a safe place. Like living in some bustling metropolis, on the largest ships you'll be able to blend in with the crowd and become an anonymous passenger among the throngs. While there are endless opportunities to socialize, chances are you won't run into the same person twice unless you try. You can meet and mingle till your heart's content, or get lost in the crowd. It' up to you.
