Looking for a movie

I'm looking for the name of an American comedy film where a bunch of high school seniors go on a field trip to Washington D.C. All sorts of stuff happens along the way in the bus and in D.C. they are accommodated to a weird motel with themed rooms, one is a dungeon and the other has a jungle theme (I recall). I also have a vague memory of a blonde Asian woman appearing in a more upscale hotel.

That's about all I can remember of it, and it was probably from the 90s. Please help!

This sounds like the National Lampoons movie about this... forget the rest of the title.
