Honestly, I would recommend a third world country (or something in that area of that economic status). I went to Belize and I can tell you that I absolutely loved the culture and the people there. Things are so much different, especially in the medical field. They still do rural visits and "tent" clinics for check-ups. Technology is in no way a dominant resource for kids and adults to exploit, therefore you get real, legitimate interactions with people. You can learn a lot from countries such as Belize. Absolutely loved it AND it was super cheap! ($5,500 for EVERYTHING)
