Icon of the Seas has around 20 total decks, with 18–19 passenger-accessible decks and 11–12 of those containing cabins, depending on how the source counts service levels. It’s laid out as a stack of themed “neighborhoods” that repeat vertically, so it feels more like a floating city than a traditional ship.

Icon of the Seas decks at a glance

  • Total decks: About 20, numbered roughly Deck 2–Deck 20.
  • Passenger decks: 18–19 decks in service for guests.
  • Decks with cabins: 11–12 decks host staterooms and suites.
  • Neighborhood concept: 8 main zones spread across multiple decks rather than confined to just one level each.
  • Vertical circulation: 22 elevators plus stairs, with some decks connected by escalator between lower levels.

Main neighborhoods and where they sit

Think of the ship as vertical “districts” stacked over several decks.

  • AquaDome: Forward, very top decks, enclosing the AquaTheater under a massive glass dome.
  • Chill Island: Multi‑deck pool area on upper open decks with several pools and bars.
  • Thrill Island: Upper outdoor decks hosting the big water slides and adrenaline attractions.
  • Surfside: A family‑focused zone midship, spanning multiple decks with kid‑oriented pools and venues.
  • The Hideaway: Elevated beach‑club style area aft on upper decks with infinity pool views.
  • Central Park: An open‑air garden neighborhood midship on higher‑mid decks, lined with restaurants and lounges.
  • Royal Promenade: Enclosed, multi‑deck indoor street through the lower‑mid levels with bars, shops, and “The Pearl” sculpture.
  • Suite Neighborhood: Clustered on upper decks with exclusive sun decks, lounges, and dining for suite guests.

Example: how a few decks are used

Each deck mixes cabins with public spaces, but some are heavy on venues while others are more residential.

  • Lower decks (around Decks 2–4): Embarkation areas, main dining, some entertainment, and access to the Royal Promenade.
  • Mid decks (around Decks 5–8): Royal Promenade, Surfside, Central Park, many restaurants, lounges, and shops.
  • Upper decks (around Decks 15–20): Pools at Chill Island, slides and thrills at Thrill Island, The Hideaway, sports areas, plus upper‑level cabins and suites.

A typical “day in the life” flow might be: breakfast near Surfside or Central Park, wander the Royal Promenade on mid decks, then head up to Chill Island or Thrill Island for pools and slides, finishing at AquaDome in the evening for shows.
