Ideally 2-6 in my experience
1-8. Within the last year, they put in a baby area
2-6 is ideal.. we went last month for a birthday party and our kids are 8 and 12 and they were out of options.. maybe my 8 year old improvised a bit..
Ages 1 to 7 would be good.
I'd say the 2-6 range suggested above is pretty accurate.
