SYMPHONY OF THE SEAS
The spa and fitness center on Symphony of the Seas is so extensive that it is considered a neighborhood in itself. It includes not only the spa but the fitness center, the salon and a restaurant (Vitality Cafe).
Whereas on most cruise ships the spa is on the upper decks, on the Oasis class it is placed relatively low on the ship on Decks 5 and 6.
