Secret sun deck While the Solarium is located on deck 15 of Allure of the Seas, a secret outdoor sundeck can be accessed from deck 14. If you take the forward elevators to deck 14 and walk all the way forward through the hallways, you'll reach a large, outdoor sun deck that not many passengers know about.

The "secret" deck on Royal Caribbean's Allure of the Seas (and other Oasis-class ships) refers to the public sun decks located at the very front of Deck 14. These wings extend out over the sides of the ship, directly above the bridge, offering a unique "captain's eye view" of the ocean and the ship's structure. To find it, you must walk to the far forward end of the stateroom hallway on Deck 14 (Port or Starboard side). At the end of the long corridor, you will find a non-descript door that looks like a crew exit but is actually open to guests. Press the automatic door button to exit onto a spacious, often empty deck. It features high-powered binoculars and a glass-floor section where you can look straight down at the water. While not listed on standard deck maps as a primary lounge, it is one of the best spots for sail-away or arriving at port, providing an unobstructed panoramic view that few passengers ever discover during their week-long voyage.
