Just that really. We are looking into taking a 6 month break from work (in so far as I have handed in my notice at work...) and spending the time traveling in South America. We are looking at doing one long volunteer stint, probably in Peru, in a school / community project, as well as seeing some of the other sights (avoiding Brazil and Colombia for safety reasons). Kids are 3 and 5.
Are we mad? Can it be done safely? Any tips would be great, thanks.
