Should be interesting to see how you compare RCCL to Carnival. Your question on what to expect from RCCL vs Carnival depends on whom you're asking. My reply would be that you should expect more than what you're use to on Carnival; but, I've been on over 40 Royal Caribbean ships and only one Carnival ship. You won't find ice cream machines in operation 24 hours a day, but if you need an ice cream fix in the middle of the night, there's always room service. I've been on the Jewel several times and consider it my favorite "Radiance" class ship. I don't know if you're going to find the food and entertainment any better than what you're use to on Carnival, but from what I hear from others, you and your wife certainly won't be disappointed. Please come back to Cruise-Chat after your cruise and let us know.
