traveling with dry ice?

[mouseketeer_mom]

So we will be the traveling MD to the Fort. DH and I will be pulling our TT with our three kids. My brother, his wife and their two kids are flying down and renting a camper from campatthefort. DH and I will be taking their "big stuff" with us (ie kids bikes, coolers etc) I will precook many of our meals and so will DS-in-law. How do I get all that frozen food down there? Dry ice? Anyone had experience with this before? Do I just thow it in a cooler and go, just like regular ice?

How long will it last? Do I need to package my frozen stuff a certain way?

If anyone has done this before and can offer advice, it would be greatly appreciated.
