Ah, this is the thorn in my Polaroid-loving side.
The problem I have with waiting to peel the film apart is that this doesn't give me a chance to take another shot if I've bollixed the first one. I like to peel it apart so I can see if I want to make any adjustments. But I still want to keep the negatives of the prints that I don't necessarily like, especially if the print is underexposed because that negative will yield better results than the one for a properly or overexposed print. It's one of the reasons so many of my shots are around my house!
The few times I've taken the Pola out and about, I've limited myself to maybe 4 shots. The prints dry relatively quickly and can be placed in a safe place in a bag, but I carry the negatives out so they can dry. I'll put two back to back so the emulsions aren't touching anything. If I take 2 more shots and place the negatives back to back, I can hold the tabs at a 90 degree angle to the other two and keep all four emulsions separate.
It's less than ideal and I've only attempted it one or two times. On other 'field' trips, I've stayed close to my car and I lay the negatives emulsion side up on the back seat. I have been trying to think of better solutions and am thinking of making myself something along the lines of a bento box, but adapted for Pola negatives. (A bento box, in case anyone doesn't know, is a stackable lunch box, like this:
