Well, we decided to bring our boy (11) and daughter (8) so there will be more children. I originally signed up for two people so I might have to contact somebody to straighten that out. Still one vehicle and the same trails.
My boy will play wiffle ball with anyone interested and the girl will have ponies, Barbies, unicorns, etc. We'll have out popup so any girls that hang out with Lily can wander in there and set up there little fantasy worlds (the whole little girls in the popup thing playing is very common). They both have DS systems too, unfortunately.
