Pretty easy answer. If you want to stay in concierge and want connecting staterooms.. jump at the Cat T and Cat V connecting. Cat Vs don't connect to each other, just with the suites. With the age of your kids, you could probably all fit in a 1BR or RS, but don't think DCL will let you book 6 in either. Enjoy your concierge cruise.. For us it is totally worth it. It is a totally different cruise in concierge.. so much more relaxing and everything is taken care of for you. My wife loves the concierge lounge with the free lattes.. Snacks are always available.. And if you get a 1BR, you can order dinner from any of the MDRs and have it delivered to your room.
