The prices are obviously the reason for considering RC over Disney. We have two boys who were so in love with the Disney characters... I am afraid they will be disappointed.
How does RC handle dining? I believe it's diff than rotational dining.
If you are just looking for a cruise, you can be very happy choosing a different cruise line. My family has wanted to go on a cruise to Norway for years. We booked one for next summer. Although
DCL is going to Norway next year, we decided to go with Royal Caribbean. The price difference between DCL and Royal Caribbean was huge, and our main purpose of us booking the cruise is to see Norway. It's a big family trip, including the extended family. I don't expect our children to be interested in using the kids club very often on this trip.
In a few weeks we will be sailing on the Disney Fantasy. We are mostly going on this cruise to enjoy a
Disney Cruise, on a Disney Ship, to see Disney characters, see Disney entertainment, and to go back to
Castaway Cay, Disney's private island.
I think you need to think about what you want. I am not "loyal" to any cruise line, and my family sails on many cruise lines, including Celebrity, NCL, Cunard, and even Carnival. You need to pick the line that is going to work best for you. If your main reason for taking the cruise is for doing "Disney" things, you aren't going to be happy on another line. If your main reason for taking the cruise is to go on vacation, then you will have a wonderful time. DCL is not the only company that does cruises well, but if you want a Disney cruise, you need to sail DCL.
For your next trip to Orlando, will you be happy if you only visit Universal? Or, at this point in your kids life, is Disney a requirement?
If your kids are going to miss the Disney characters, perhaps you should save Royal Caribbean for when they are older.
