Find Your Cruise
Why not read the individual reviews of the ships on cruise critic to see. This is taken from the review of the Sun Princess "Fitness & Recreation
On the main pool deck there are two central pools (these get crowded in good weather). A third, a splash pool, is located behind the fitness center, surrounded by sunning decks and serviced by an outdoor Splash Bar (open in good weather); there are ample sun loungers. The topmost passenger deck, Sun Deck, is divided into two portions. The aft portion of Sun Deck is available for sports activities like shuffleboard, basketball and paddle tennis. Other recreational features include a a golf simulator and quoits.
The Lotus Spa, with its attractive Asian themed decor, offers numerous treatments for men, women and even teens. The adjacent workout room features the latest machines and weights with piped music and (silent) TV screens (one nice touch: While the ship was sailing the College Fjords, the spinning class was brought outdoors.) There is a carpeted space for yoga, aerobics and Pilates (extra charge).
Sea Princess has one.
I would say all of them. Check out each ship description at www.princesscruises.co.uk kind regard.
