go vacation is good fun for all the family.
there are 50+ activities, some are very much aimed towards the kids, but after completing an activity the first time you unlock all the different skill levels and variations on the activities.
basically think wii sports resort with the ability to freely roam 4 large resorts using one of around 12 fully controlable methtods of transport:
off road car
atv (quad bike)
marine bike (jetski)
snowtubes (inflatable doughnut)
oh and you can run and swim.
