Last minute change of plans for combinded bachelorette/bachelor party!

So to make a long story short, last minute (a week from our combinded party) a ton of people backed out last minute. My maid of honor “double booked herself” and isn’t coming (I’m livid) my other bridesmaid who decided to plan it because after serveral attempts to reach out to my MOH about planning it she never responded. But anywho that bridesmaid came to me about an idea to get a party bus and drive around Detroit, she then last minute started stressing about money and I basically knew something would fall through because nothing is ever that easy with any of my friends, so yeah when a ton of people backed out I just told her to forget the party bus because they are expensive. We ended up deciding to get 2 campsites and camp over night, grill and just hang out. I’m totally okay with this option, but does anyone have suggestions on things we can do the night off that is both male and female friendly? Any fun games?
