Ideas for 9 year old boy, in PA, for a birthday activity?

Hey I am looking for Ideas to do in April with my cousin,a 9 year old boy. I asked him what he wants to do for his birthday and he gave me a list of 5 things he would like to do. The list was go-cart racing, skyzone, amusement park with rides, water park, and laser tag. My budget is about 100 dollars for 3 people and I want to find a place that incorporates many of the things on his list. Does anybody have any suggestions of a place that would be fun for a nine year old boy and incorporates multiple of the activities he wishes to do, for cheap? I live in Dauphin County Pennsylvania and wouldn’t be looking to travel more than 2.5 hours. Thank you so much!
