This! We're cruising RCCL on the Wonder in January 2025. Since we were traveling from out west, the wife suggested maybe we look at a 5-day on the Wish after our Wonder cruise as we hadn't been on DCL for a few years. Pricing this cruise was basically what we paid for our 7-day eastern Carribean on Royal or, as you said, 30%+ more than the exact same cruise on Utopia (except for the Coco cay vs Castaway). Guesss which one we booked!Price. I'm currently shopping cruises and the same itinerary (minus perfect day vs castaway) is 30% cheaper on RC Utopia of the Seas. That is too big of a gap for me to justify.
