I have heard of a place nearby that has indoor inflatables for kids but I have not yet been able to go. Anything that provides exercise and tuckers my kids out at the end of the day is Aces in my book. Also my kiddos are at the age where the bounce houses and other inflatables are no longer scary as long as there are similar aged kids in there with them.
And once they are inside- watch out. We have to lure them out with promises of chocolate and strawberry milk, both are always a hit.
