Thinking about taking an Learn Spanish program in Guadalajara, MX, what questions should I ask.
I've researched the internet for all of the schools in Guad, but beside cost of program and length, what other questions should I ask to make sure that I get the best possible experience.

Why are all spanish language schools so bad?

Are there any schools in MX or S. America that focus solely on learning Spanish, like 40+ hours per week. With one on one tutor style teaching. Are there any schools that dont waste time on salsa lessons and surfing.
-Also any schools with nice hotel right next door. I do not want to do homestay.
