Travelling....?

It has become blatantly apparent that my best friends (two separate groups of best friends), want to do some road trips. That's cool and dandy, but they both want to do them to the same place at around the same time of the year. Has anyone else come across a situation like this before? Or does anyone even have two separate but equally loved groups of best friends that don't intermingle with one another?
I am contemplating the idea of having the two groups mesh and go together on the road trip together, but both groups are totally different.

Group 1, I met them all in middle school and are extremely smart and driven people, who like to joke around a lot, especially towards one specific friend in that group. Nevertheless, they are more the "straight-laced" type of people.

Group 2 and me became best friends in high school, since Group 1 went to different high schools than me. However, Group 2 does a lot of active things like going jet skiing, snowboarding, ATV riding, playing loads of video games, etc. This group of friends, how should I say, more relaxed, go-with-the-flow, partying type? Well, at least more so than Group 1.

Therefore, I just don't know. I know Group 1 knows one of the girls in Group 2, but the Group 2 girl doesn't really like one of the girls in Group 1, so that's already a red flag. Sigh. I really hate being in the middle, especially in this situation, because I will have to tell one of the groups that I can't go with them. Ahhh, I think the Groups should fight for who I go on the road trip with, or at least bribe me. If only that was a plausible resolution.
