I think the main problem, and again, this is in current day situation as opposed to back then, is that people could know where the strings are and try to grab one and wrap it around their fingers or something. Instead of the string breaking, it could cause potential damage.
Aashee, I don't think its creepy to take a doombuggy ride with anyone. In fact, there was one guy I met during HMH, we rode around several times, both of us giving knowledge about mansion and things. He had a camcorder with him. I know he was a pretty big Disney nut and stuff though. We just shared quite a bit of info about the ride with each other. Fun times. YAY MANSION!
