G-Raff, learning a language abroad is the only way to make sure you practice what you learn. It's also easier to learn this way as you are forced to speak in the local language.
I haven't looked at your link, but make sure the course isn't too intensive as I'm sure Jilly Gould did something like this in Spain and the lessons were about 4-5 hours long, which she felt was slightly too long per lesson.
