Smoking onboard the Oasis of the Seas
Smoking in public areas is only permitted in designated smoking sections, which vary by ship. Generally, smoking is permitted outdoors on only one side of the ship; smoking is no longer permitted on balconies, and never permitted in cabins. Signs are posted at the designated smoking areas and if in doubt, ask a staff member about where smoking is permitted.
Designated smoking areas can be found on 1/2 of Deck 15, and in half of the casino. There's a smoking area in Blaze, on the second floor of Dazzles, and at the bar in both the Latin bar and the English pub.
