Semester at Sea

Has anyone worked on the boat taking students for a semester at sea (University of Va) or known anyone who has? I saw a posting for a staff nurse requiring five years in the field with critical care/ED/college student health experience plus ACLS. I just barely meet each requirement but want to know if anyone out here had actually done it. I didn't count, but it looked like the fall of 2013 voyage had close to 15 country visits. Doesn't it sound amazing?
I mean, excepting the fact that the patient population would consist of brats whose parents had an extra 30k to send them on a semester at sea to begin with. Sense any jealousy. Lol.

If you do it, post back about it. It would be great to hear about!
