Irons and ironing boards are not allowed because of fire hazards. Royal Caribbean does not have self-serve laundromats either, so your only choice is to use the ship's laundry and pressing service. I think clothes steamers are allowed but we don't mess with it anymore.
Dave is correct...no ironing boards or irons in rooms. We have a small steamer that gets the job done and have never had a problem. Would like to try the dry cleaners plastic trick!
We always bring a spray can of Wrinkle Free...works pretty good...but nobody really cares if you have wrinkled clothes....always can hang them in the shower....Just have a Great Cruise.....wrinkles and all...
You will LOVE the Oasis....23 cruises and I have to say it was the best one ever...and only because of the ship.....Planning on taking the Allure when she gets here....
