If your DD has never been to WDW, then do the land/sea. If she has, then do what you want. Just remember that a 7 night cruise is usually just as much as the land/sea packages, so you might want to consider that as well. We took the 4 night Wonder in November and it was just too short to do as a vacation in itself. Perfect if combining with a WDW stay though. We're taking a 7 night next Nov, since the 4 night was too short for us.
