Decided to try Radiance after sailing with other lines. Beautiful ship although extremely crowded.
Great dining and service. Also recommend package for specialty restaurants but be wary that in the Japanese Izuma although you pre-paid, you will be slugged a $5 cover charge and your choice is limited to $15. After that, you pay through the nose. The Chef's Table was really great and worth the money. Highly recommended.
Verandah cabin satisfactory although bathroom very small and still with a tiny shower and curtain. Wonderful service from our cabin steward.
Public rooms very good. Entertainment ok but nothing to rave about.
Big negative - on this trip there were hundreds of children many of whom were not supervised undisciplined and unruly. Perhaps there should be a limit on the number as is on some cruise lines. We even had to call security when young teens were rumbling, wrestling at the dining table and racing through the diners. This ruined the trip for many adults. Likewise, a pool attendant/ security lifeguard is recommended for the swimming pool for the same reason.
For families - go for it - but if you are mature or a honeymooner then try a more sedate ship.
