Odyssey of the Seas vs Spectrum of the Seas: which costs less right now?

Same Quantum class hardware, Royal Caribbean International — the price difference is itinerary, season, and demand, from fares observed October 16, 2026.

Same ship class means near-identical hardware — sister ships share hull, capacity class, and most amenities. Price only, like every rank on this site: nothing here scores food, service, or what a fare includes.
