I wouldn't say it's odd, but ask yourself if YOU feel safe doing it. If you don't, is there something you can do to make you feel safer?
It may have no mobile signal but does the house have a landline phone for you to make a check-in call with other friends or your parents?
Does someone outside of the group know the address of where you're going and what day you'll be heading back to where there's signal? Can you turn on location sharing in your phone with some people you trust? Is there a way for you to meet up with these guys before hand to get a vibe check on them?
It's good that you want to push yourself outside of your comfort zone, but do not feel bad saying "no, I don't want to do that" if YOU don't feel safe.
If you feel safe then great, have fun, and let us know how it went 😊
Commenting to say I support this statement 100% in it's entirety. This is good advice OP.
