most helpful! Been going crazy trying to pre-schedule from Mexico City to Acapulco. I now understand why I can't find anything - no direct service from Terminal Norte to the south! Finally found a bus line with premier service to Acapulco - but their web page is all in Flash and none of the links work right LOL - but at least now we have a plan. Go to the Tasqueña terminal on the south side, look at all the different lines and find the best deal, service and time for Acapulco. Bueno.
