I did my CELTA course at their center in Montanita a few years back, and it was a nightmare. Everything these guys are writing on here sounds true. As for the CELTA program, it was quite disorganized, and they didn't even bother going over crucial teaching approaches such as Desuggestopedia, content-based learning, community language learning, silent way and soforth. They just give a very superficial understanding of communicative language teaching. They also pay practice students to be there sometimes. It was a total waste of time and money. The director and his wife are both hacks too.
