Mariner of the Seas
This isn’t your same-old, never bold weekend. This is a boredom busting getaway for the whole crew. The amped up Mariner of the Seas® is packed with more ways to play on the most maxed-out short getaway ever. Hang ten on the added FlowRider®* surf simulator or race down The Perfect Storm℠ waterslides. Bond over family-style Tuscan eats at Jamie’s Italian by Jamie Oliver, or kick off date night at The Bamboo Room. Ditch the road trip for an action-packed cruise ship, with quick cruises sailing from Orlando.
