Overall I love NCL (Getaway & Breakaway so much better for older kids than
DCL). I also would never go DCL on a port-intensive cruise - kind of waste of money IMO. And having cruised Alaska twice - love a balcony. (I so enjoyed seeing whales early in the morning from my balcony.) And of course Glacier Bay beats Tracy Arm. For those reasons NCL should be a slam dunk. But....in this case I would recommend DCL because your kids are at a great Disney age (even for the shows) and the NCL port times are really terrible! I wouldn't be impressed with either the Wonder or an older, smaller NCL ship (sorry I missed which ship?). If it was just you and husband, hands-down, NCL. But keeping the kids happy always makes for a better vacation....and I think they'd enjoy DCL more.
