Of the ones I have been on, I would rank them:
Freedom Class
Later Voyager class with glass balconies
Earlier Voyager class
Oasis class
Have only been on Oasis once, and it was during Thanksgiving week. We normally don’t cruise during school breaks like that so want to try that class again during our normal off-peak travel times. Also interested in trying Radiance class at some point as so many people rave about them.
Also a special shout out to Sovereign class which was the first cruise I went on. Crazy to think that 30 years ago, those were the largest ships in the world.
