Having been on all the classes of RCCL ships, I agree with others; we like the Radiance-class over the others.
With that said, can't wait to see the new Quantum-class ships. Larger than the Freedom-class and smaller than the Oasis-class, so it may be a bit too large for us.
But I have to admit that the Solstice-class of the Celebrity fleet have to be our all-time favorite so far.
47 Cruises & Counting! Favorites: Paul Gauguin to Tahiti: Uniworld River Cruises in Europe; any of the Celebrity Solstice-class ships; Holland America for 12-nights in the Baltics & Russia; RCCL for 14-night Greek Isles, Turkey, & Croatia; Holland America for 14-day Alaska cruisetour; 10-night Canada/New England cruise; 21 days in Hawaii including a 7-night NCL cruise; Oceania for 25 days in Asia; & 3 months touring Europe by train. And many days spent in all-inclusive resorts!
