Man, I never went on a multiple day field trips for school.  I was lucky to get 1 field trip a year.  And then all we ever did was go to Elachee Nature Center in Oakwood.  It was pretty cool though.  You got to play with this robotic T-Rex and go on a hike.  So.. it was fun.  
Lucky for me, in high school I knew which classes to pick, that plus I love art.  But our art class would usually go to the High Museum of Art each semester.
