My son(15 y.o) and me had a vacation in Maribel at the second part of January 2011. We had never alpine skied before. Our friends, who had arrived there before us, recommended us David (First Tracks) by very good recommendations of excellent coach, and in general a very nice person. And I would say it was true! His individual approach and well-organised lessons helped us to fill assurance on the piste on the fourth day of our stay there.
Moreover, David is very good company, knows a lot about local infrastructure and has a lot to talk about.
Enjoy your stay there !
