This is the first idea that you should take a roll(s) of duct(duck) tape and if someone breaks curfew they get taped to their bed/wall for an extended period of time.

That wasn't probably the best idea. So I'll try to offer others.

No playing with robot if you break curfew.

Set the rules early, give consequences (ie,. can't watch competition), make them sign it before you go on trip, and hold them to it.

Don't set ridiculous curfews like 9, or 10. 10:30 - 11:00 is a better curfew time or more if you are willing to stay up and then wake up the next morning.

Set a rigid schedule (ie. 8:00pm go to eat, 9:30 team meeting, 10:30 in rooms, 11:00 lights out).

If you break curfew you can't travel to the next competition. This with the driver's rule would catch most people.

Be creative. Hold a team meeting at 1:00 am when you discover that person and talk to the whole team without ever mentioning that person name while you glare at them. Say how you are dissapointed with this individual and such.
