Mariner Of The Seas deck 15 plan (Escape Room)

(drydock 2018 refurbishment) On Deck 15, the "Skylight Chapel" (wedding room) was replaced with "The Observatorium" (Escape Room by Puzzle Break). The new venue provides adventure game experiences (team-building exercises) for a group of players who solve a series of puzzles by using clues, hints and group strategy. The team is given a set time limit to solve the puzzle (secret plot hidden within the room).

Skylight Wedding Chapel (nondenominational, capacity 45 seats) was used for religious services. It featured a stained glass window (allowing natural skylight) overhanging the altar and also mural artwork. Here were held Royal Caribbean cruise weddings and vow-renewal ceremonies at sea (no masses).
