Icon of the Seas Deck 4 Deck Plan
Read the Deck 4 plan from front to back. The Royal Theater fills the front of the deck. Behind the forward elevators is the upper level of Music Hall, with its own bar, and then Casino Royale, with a bar in the middle and an escalator on the starboard side up to Deck 5 and down to Deck 2. The middle level of the Dining Room is behind the aft elevators. Ocean View rooms run in one long row down each side of the ship.
The Royal Theater
The Royal Theater spans Decks 4 and 5, with the main seating on Deck 4, and Royal Caribbean lists it at 1,210 seats. It’s home to The Wizard of Oz, which Royal Caribbean says is only on Icon of the Seas. Shows are included in your fare.
Royal Caribbean strongly recommends reserving seats in the Royal app or My Royal Cruise. Reservations open the first day of the month before your sailing and close online four days before you sail. After that, you can book on board.
Casino Royale and Music Hall
- Casino Royale: Royal Caribbean allows smoking in the casino, with separate smoking and non-smoking areas. You must be 18 to gamble. Kids may walk through, but they can’t linger or be left there.
- Music Hall: the upper level of a two-level live music venue that starts on Deck 3, with rock cover bands and a DJ. Royal Caribbean lists it as included; drinks cost extra.
- Dining Room: Deck 4 is the middle of the Dining Room’s three levels. Dinner is included, and you choose set-time dining or My Time Dining when you book.
Ocean View Staterooms on Deck 4
Deck 4 has 104 Ocean View rooms, each with a window and no balcony, at about 160 to 187 square feet. Here’s how they sleep, from the symbols on Royal Caribbean’s plan:
- Sleeps 4: 26 rooms, more than half of the 48 Ocean View rooms on the ship that sleep 4.
- Sleeps 3: 74 rooms.
- Sleeps 2: 4166, 4168, 4566 and 4568, beside the forward elevators.
The eight Interior rooms, 4577 to 4591, sleep 2 and sit beside Music Hall.
Six pairs of Ocean View rooms connect: 4178 and 4180, 4190 and 4192, 4262 and 4264, 4578 and 4580, 4590 and 4592, and 4662 and 4664. Each pair joins a room that sleeps 3 with one that sleeps 4, for up to 7 people side by side.
Accessible Rooms and Obstructed Views on Deck 4
Deck 4 has four wheelchair-accessible staterooms: 4268, 4270, 4668 and 4670. All four are Ocean View rooms that sleep 3, beside the aft elevators.
Royal Caribbean’s plan marks 36 Deck 4 rooms as obstructed views, including all four accessible rooms. Royal Caribbean doesn’t publish what blocks each one, so we check the plan symbol for the exact room before we book.
Quietest and Noisiest Cabins on Deck 4
- Near Music Hall: Guest reviews suggest light sleepers avoid 4180 to 4200 and the interior rooms 4577 to 4591, which sit next to Music Hall’s late-night music.
- Below you: mostly Deck 3 staterooms, and no venue.
- Above you: the outdoor walking and running track on Deck 5 runs along the outside of the ship over these rows. We haven’t found reports of noise from it.
- Watch the elevator lobbies: rooms right beside the forward and aft elevators get more hallway traffic.
Is Deck 4 a Good Deck for Families?
Yes, Deck 4 is a good value deck for families on Icon of the Seas, with 26 rooms that sleep 4, connecting pairs for up to 7, and the theater, casino and Dining Room on the same deck. It has no balconies, the plan marks many rooms as obstructed views, and light sleepers should avoid the rooms near Music Hall.

Frequently Asked Questions About Icon of the Seas Deck 4
What is on Deck 4 of Icon of the Seas?
Deck 4 on Icon of the Seas has 112 staterooms, numbered 4166 to 4670, plus the main level of the Royal Theater, the upper level of Music Hall, Casino Royale and the middle level of the Dining Room. Most rooms are Ocean View rooms with a window; there are no balconies or suites. What that means for your family: a show, dinner and a little live music are all a short walk from your door on this deck.
What deck is the casino on Icon of the Seas?
Casino Royale on Icon of the Seas is on Deck 4, in the middle of the ship between Music Hall and the Dining Room. An escalator beside it runs up to the Royal Promenade on Deck 5 and down to the gangway on Deck 2. You must be 18 to gamble. Kids may walk through the casino but can’t linger or be left there. The truth is, it’s easy to route the grandkids around it on the way to dinner.
Is smoking allowed in the casino on Icon of the Seas?
Yes, Royal Caribbean allows smoking in Casino Royale on Icon of the Seas, with separate smoking and non-smoking areas. News reports describe the non-smoking areas on Icon Class ships as small, and you may have to walk through the main casino to reach them. Casino Royale is on Deck 4, in the middle of the ship. Here’s what I tell grandparents traveling with kids or anyone sensitive to smoke: take the aft elevators straight to the Dining Room instead of walking through the casino, since the escalator from Deck 5 lands right beside Casino Royale.
Do you need to reserve Royal Theater shows on Icon of the Seas?
Royal Theater shows on Icon of the Seas are included in your fare, and Royal Caribbean strongly recommends reserving ahead. Reservations open in the Royal app or My Royal Cruise on the first day of the month before your sailing and close online four days before you sail; after that, you can book on board. The theater spans Decks 4 and 5 and seats 1,210. In fact, booking The Wizard of Oz early is the easiest way to get a show time that fits little ones.
Which Deck 4 cabins are noisy on Icon of the Seas?
On Icon of the Seas Deck 4, guest reviews suggest light sleepers avoid 4180 to 4200 and the interior rooms 4577 to 4591, which sit next to Music Hall, a late-night live music venue. Below the outer rows are mostly Deck 3 staterooms, with no venue, and above them is Deck 5’s outdoor track. Rooms by the elevators get more hallway traffic. The simple test I use: the farther from Music Hall, the better the sleep on this deck.
Are there accessible cabins on Deck 4 of Icon of the Seas?
Yes, Icon of the Seas Deck 4 has 4 wheelchair-accessible staterooms: 4268, 4270, 4668 and 4670. All four are Ocean View rooms that sleep 3, beside the aft elevators, and Royal Caribbean’s plan marks them as obstructed views. They’re the lowest accessible rooms on the ship, close to the Dining Room. If anyone in your group uses a wheelchair or a scooter, tell your advisor at the start, since these rooms can go early.
