Would you find this weird?

I met some people at a hostel a few months ago, and unfortunately didn't manage to get anyone's Instagram. Through the page of the hostel, I found someone's Instagram account and through that I found the others. would it be weird to message them and ask to add them? This is just for a connection but it has been a few months. I don't meet new people that often unfortunately.
