Ship notes · Mariner of the Seas

Recently refreshed, and an easy size to manage.

Mariner is Adventure's sister — Voyager class, about 3,300 guests, 14 lifts across 14 passenger decks. She was Royal Amplified in 2018 and refurbished again in early 2026, so she's the most recently updated of the mid-size ships here.

Refit moved things — confirm the cabin

Ask for the accessible cabin count for your sailing

Voyager-class ships carry in the region of 26 to 27 wheelchair-accessible staterooms among roughly 1,670 — but Mariner has been through two refits, and refits move cabins. Get the cabin number and its features in writing rather than relying on a deck plan you found online.

Getting around the ship

What the 2026 refurbishment means for you

The same logic as Adventure

Mid-size means less walking than a mega-ship while keeping 14 lifts and a full set of venues. If distance or queueing is what costs you, the Voyager ships deserve a look before the giants.
