Back-to-Back Cruises on Mariner of the Seas

Every row below is a real pair of sailings on Mariner of the Seas herself, where the second leg leaves the day the first one returns — so you stay aboard for 9 to 24 nights instead of flying home in between. There are 35 of them cached right now, out of New Orleans, Galveston and Barcelona, departing between Sep 19, 2026 and Apr 8, 2028. The most common combination is 14 nights (18 of them). Fares are the lowest cached interior all-in price per guest for both legs together, before any casino offer is applied.

About the Voyager Class

The revolutionary class that first put a Royal Promenade, an ice-skating rink, and a rock-climbing wall on a cruise ship. Voyager ships walked so the Oasis class could run, and they remain roomy, well-loved workhorses.

Want the other ships too? Our back-to-back cruise pages list every pair of Royal Caribbean sailings that currently connect, home port by home port — including the ones that switch ship between legs, which this page leaves out.
