Check out the specials. Weekday racing is a great deal for ~$10. Ropes course , bazooka and roller skating are all around $10-15. Arcades are pay as you go. Food and drinks/beer are here too. So to can spend about 25-45 per person and have a blast. Trampolines are not part of Xtreme but located inside.

Depends on what you'd like to do. The trampoline park is about $15 per person depending on your time choice, escape rooms start at $36 per person, the rope walk is $10 per person, etc... It gets pricey once you start adding it up.
