I might have to agree with Wade on this. Seven weeks of vacation, LOL, I can't complain, I get 6 weeks but 4 is official and the other two is more or less unofficial, depending on snow days.
Anyway, I understand you won't want to wait until you came back to start this, I would try and keep it frozen until you get to where you are going, then defrost and ferment, when bringing it home, keep it in a carboy and make sure you insulate that carboy. Your goal coming home is to keep it from moving as much as possible.
Please keep us posted on your progress, I am sure there are others who would love to know if this is possible.
