FWIW - I grabbed up some more 3000 this month. But I noticed I had a couple frames left in my RB back, expired 2011 - that back lived in a warm closet (our downstairs heater exhaust pipe is routed through that closet, so warm winters and warm texas summers) and the film worked fine.
The stuff is more robust than you think, but keeping it cool (never freeze it!!!) is supposed to be a good strategy. Our wine cooler has a space under the bottom rack that will hold about a dozen boxes, mine lives there now. Polaroid and Bordeaux in the same fridge? I should call it the heaven cabinet!
Many people over the years have addressed transporting the prints - they do dry very fast, but if you really do this often, I'd try something like a shoebox and a glue gun and some cardboard... make something with dividers (kind of like those old CD racks) that only touch the borders and keep the print upright and separated.
