awesome idea! I've been looking for ways to finally become fluent and this will probably be a great help! I was also thinking of visiting another country for a month. Do you have any resources for doing this that are cost effective? Thanks a bunch!
About the resources you mentioned, there are several offers, depending on what you want: from inmersion courses to courses in Spanish schools/universities.
I suppose you'd like to visit a country in Central or South America? Please, let me know and I'll try to find something interesting. Anyway, if anyone in this forum knows about this, please give us your oppinions! ;-)
