Just got back today. Great suggestions. Well I spent about 30$ eating Subway and McDonalds. It worked but not the most healthy. I have been doing that for the last year now. I liked usmc-sgt. idea. Although that would require my wife to cook. I might need to buy one of them mini coolers that clip on to my bag. I also bought some cookies out of the vending machine at the hotel and they were great for a 3 hour flight. I liked the frozen burrito idea too. I would think that would go bad by the third day though.
