If you have never been to a third world country before, you have this picture of poor starving people with nothing. Once they have visited, they see what it is really like. They just want to make sure they have "the essentials" for their happy vacation. After one visit, they realize it is really pretty civilized after all.
My daughter lives in Italy (Tuscany to be exact). She has me send her things like peanut butter, Kool-aid, brown sugar, beef jerky, and (now don't laugh TOO hard) Kraft Macaroni and Cheese (in the blue box)...lol. My grandson missed that a lot at first. Now he hardly eats it anymore. There are just certain things that you can't get there. If you grew up here and are used to them, it is a big deal. I had a rather odd image of Italy before I went there myself. As far as Belize goes, I can't remember what I expected on my first visit but whatever it was, I fell in love with the place and the people.
