I'm no minivan/caravan freak but I thought that the "Swivel 'N Go" seating was an interesting feature. It makes sense to me, considering the number of board games that have been interrupted by chumps who don't have rides and how sometimes you want to turn and talk to the people in the very back.
I've been having way too much fun thinking about things to do with such an arrangement. Here's my list thus far:
Conversations on a long drive
Quick pog tournament
Tea and biscuits
Anyone care to add ideas?
