For families where everyone can (and is willing to) participate - it's a blast!
We always enjoyed it as DINKs, but I wouldn't recommend it unless you have slightly older kids than we do now (ours are both under 4). If your kids can play interactive games well, then they will have a blast, otherwise, it's not worth it for little ones - they just won't "get it".
Our faves were the Virtual Pirates of the Carribean, the Virtual Jungle Cruise, the remote control treasure hunting cars in the floor by the VJC, and the Buzz Lightyear Bumper Cars. Everyone gets to be a part of those games, be it manning cannons, paddling oars, yelling "Turn LEFT - NO!!!!!! RIGHT!!!!! NO!!!!", or driving over balls and then getting hit so your car spins like mad.
