Well ..see ... you are not allowed to put thoughts in their minds and words in their mouths. This kind of verthinking stuff that comes to you with earnest heart and pure joy is ruining the fun for everyone: the deed of having some adult game of their own design, starring themselves, for the purpose of filling up their downtime, as opposed to watching the many reality dating or cheating game shows on the tele.  That should be your motivation. simple, clean, small talk and easy going conversations making for a carefree fun ride along with some sweethearts ready to play and have fun alongside MC.
Countless band members have admitted to hooking up on the tour. Heck, The Weekend did a whole Movie about hooking up with a smals, catfishing, jailbait looking fan and presented it like his comeuppance therapy sex bender, taking him out of a shitty touring performance and downward spiral out of his humanity - the result was a spectacular dumpsterfire backlash from everyone seeing this as what it actually is - hedonistic self agrandising while also self deprecation, full of himself, a victimizing and self-pitying pledge for all the world to see.
Have fun and be there for that it is worth: careless fun with disposable guys, the thing they might be used to doing all the time during their long far away tours. MC is not looking for any relationship; game is not forcing it and the girls are not wanting it either. Win+win!
