Love DCL (I've done 2 14 nights and a 4 night), but also love RCCL. We did a family cruise a few years ago on Royal and had a great time (kids are all between 24 and 31 now), quality wise I found them both to be equal, I like the rotational dining on DCL a lot but RCCL has a lot more for the 20-30 crowd to do.
