We've been on 20+ cruises with Royal and Celebrity. Anthem pushed us over the edge and I think we're now done with Royal. Food was problematic. Express walk-off was the most stressful one ever (and we always do express walk-off). The rewards points system in the casino reset after the first two days and there was confusion as to what they would do to fix it; originally they told us we'd simply have to forego to the freebies that the lost points would have entitled us to.
We ate every night in a speciality restaurant and the food was mediocre at best. Even the waiters cautioned us against some the menu selections due to poor quality.
Wonderland was not our thing. We like Qsine on Celebrity which has an imaginative menu so I thought we'd like Wonderland but the menu includes many items that are acquired tastes. Our speciality cocktails were also bad.
Spacious. No ship noise.
