re: My son and 2 friends....

I have done this before with 20 somethings with a major brand. I will say that I was a very loyal member at the time and I always called the hotel. He used his own CC to check in for incidentals but my card was on the room. No problem but my son didn't raise hell or tear the place up either. It was a non-event.

Now rental cars are a whole different story. Not much wiggle room on those if the renter is under 25.
