This was our 41st cruise, 28th with RCCL, so we have a pretty good idea of what works and what doesn't. If you haven't booked a cruise yet and are not in your 20's or with a big family group, we suggest you stick with the Voyager or Freedom class ships.
That said, if you are already booked, here are our thoughts (By the way the Lido blog on this site is excellent!)
The Positives:
Stateroom was smaller than usual but the space was well utilized. 8th floor aft was a great area for staterooms, central to all.
