I really don't see anything about a section or area for kids. Is this family friendly (meaning our 3 year old will find things to enjoy)? I think my older kids would enjoy this but worried about bringing everyone.

You might want to consider a family craft night for your younger child.

Generally, not much fun for a 3year-old

I think your kids will be bored.

I'm not completely sure. I worked a party there and it's quite colorful and uses a lot of shapes in the architecture and decorations. Might be a bit much for a 3 year old or just interesting enough for them to get engaged.
