Go on Splash as the sun is coming up. That is still a peak experience in my mind from my Grad Nite (especially when you're winding along in the flume near the beginning at the top of the mountain). It's something you will never have the opportunity to do again.
Other than that, just have fun, and don't let fatigue overcome you! You can sleep later - play the whole night!
I did Grad Nite back in 2000 (I know, I'm old) and in 1999 as a Junior. Keep awake is all I can say. That and comfy shoes. When I went they were running the Mark Twain with a DJ from KROQ around the Rivers of America. They played The Violent Femmes' "Add It Up" around the backside of TSI *uncensored.* It was a truly bizarre experience hearing about 100 or so teenagers shouting the F word at the top of their lungs.

To anyone going to any of the Grad Nites.....If you are asked a question by the Security Officers doing the screening prior to entering the park, think twice about being a smartass. Last week there was a grad who thought he'd be funny when asked a question and he gave a very ignorant
reply ( I won't go into the details). The end result is he went straight from the turnstiles to the detention center where he spent the entire night with his chaperone. Your supposed to be there to have a great time, don't end it before it even gets started by saying something stupid when asked a question by Security.
