Jim, You should make this the tipical night in Maine. Most college kids don't take Friday classes. If you made them feel like it was their bar, they may come back every Tursday Night. Bars here hold college night parties on Thursday. Just name the night after the local college and the kids flock in because it belongs to them.
You could double what you are being paid for the night by making it the only place to be on Thursday. This is how I have approached all of my Club work. The place makes money, I get paid!

Good luck!
