Baby shower !

So I’m going to have my toddler and nieces and nephews at my baby shower.

I’m thinking of renting out this building close by that has a kitchen in it to have the baby shower.

I need ideas on how to entertain the kids.

Baby shower will be towards the end of October/beginning of November and the building is to close to the road so the kids will have to stay in the building.

Any advice / ideas ?
