If your inviting them, you should pay but you always just tell them how badly you want to have a party at Sky Zone, but can't afford it and see if they suggest paying for themselves.

I Was Suppose To Be Having This Big Party At A Venue But The Person I Was Suppose To Have It With Flaked Out, So I Decided That I Wanted To Go To Sky Zone With My 3 Best Friends & Maybe Out To Eat I'm Not Sure If I Should Pay For Them To Go To Skyzone Or If They Should Pay By For Themselves. We're All 16-17 Years Old! It's About $21 Per Person For 120 Mins!
