You're already spending a fair amount for this vacation so spring for a Polar Bear!! DO NOT try a Styrofoam/plastic cooler as you'll waste enough in food to have easily paid for a Polar Bear. We take our 24 pack with steaks, fish, bolognaise sauce that I vacuum seal then freeze. Never any need for ice of any sort and don't even attempt to fill up the 1/3 empty space with any type filler and it always gets to our villa after a 12 hour travel day frozen solid! <img src="http://www.traveltalkonline.com/forums/images/graemlins/Clapping.gif" alt="" />
