Visiting Mexico City and Language schools... March to end April 2008

Hey there,

I am visiting Mexico City from Friday 14th March to 27th April... I will be travelling in Mexico during these dates and may have a short trip to Lima and possibly Bs As but my main purpose is to improve my limited Spanish. Anyway if anyone wants to meet for a drink it will be cool to meet you.... Also if anyone can reccomend a language school which is not prohibitively expensive I would be grateful
