I know the feeling.
I was in Vegas. Stayed at Circus Circus (A dump, btw) and we had to check out at 10am.
And our flight didn't leave till 10pm, and we had to be at the airport by 8pm.
Longest day of my life.
We also managed to drink a bottle of Crown Royal in 10 minutes, because my (idiot) friend decided to put it onto his carry on.

Those hours flew by.
