Vacations with Purpose and Fun?

I heard about these vacations a while ago and thought they were interesting.  Basically, you book a vacation to a place to test out a trade or job.  Maybe your dream job is to be a brew master,voiceover artist, organic farmer or who knows.  You can test out quite a few different options through www.vocationvacations.com.    I always thought that being a voice over artist would be fun but after hearing myself on my voicemail I have decided that a twelve year old nasally voice wouldn't be in high demand.  That is what all the Disney kids are for.  But there are others that would be interesting to try out.  Pastry chef, flyfishing outfitter, jewelry designer,  I obviously need to give this more thought.  Maybe when I get a better idea of what direction I want to move in I will give it a go.
