Disney!!!!!!! Clean, family, entertainment, done very well. On the 5nt dream, there were 3 production shows done VERY well. "Believe" actually brought me to tears - my hubby too!". One night, we also had the lavenous Mike Super (love him!!!!!). I had previously seen him on Carnival Dream, and he was excellent then too.
Royal shows were very good. On FOTS, they had one excellent production show which I would compare to Disney.
On HAL, I found the production shows to be "lawrence welk" in nature. I wasn't impressed. They also had one very lame comedian/juggling act. We did not want to be rude and walk out, but it was tempting! What I did like about HAL was the selection of live music in the various lounges.
But I would give the overall to Carnival. In my opionion, Carnival has the best combination of production shows and comedians. I think they offered two seatings of the comedy show every night. I enjoy comedy so this was great.
