They should have a list of "classes still open" nailed up by the registration room. Take a look at that to get an idea of what's available. I hear underwater basket weaving is hecka fun. ;)

On an unrelated note, let me know if you have to work on the 4th, and I'll make arrangements as needed. Because of my hair/waxing appts, I won't be running around until 12:30 or so, and I suspect that would be smack-dab in the middle of your shift... :-P
