I've been racking my brain for many years trying to figure out what movie this was from, you can probably understand just how hard it has been to try to Google this when I only remember a few scenes from the movie:
It was a college road trip sort of movie I believe where a class or group of students went on a trip with their teacher/s.
In one scene the movies "fat and stupid" guy is bugging the leader/teacher who is talking to the receptionist at the place so either the leader or the receptionist takes a handful of candies/mints and throws on the ground behind them to make the fat guy run after it.
In one scene the students have spiked the "hot teacher"s chocolate box with liquor to try to get her to strip in front of a two-way mirror, and one student is sent in to sort of seduce the drunk teacher.
I believe there was one super creepy nerd who had a cardboard cutout of some actor who he worshiped.
I'm sorry to be so vague, we rented this movie on VHS so long ago and this is literally the only scenes I remember.
