The main trip will be one week - 20th - 27th March 2010 but the instructor (www.easiski.com) is organising groups for the week before this too. There will be lessons in groups of max 4 people and the groups will be organised to suit the ability of those who book.
We're in the early stages of organisation as yet. Travel needs to be arranged independently - I am going by train, leaving Paris at 1338 Sat 20th, Train iDTGV 2949. Tickets aren't normally available until 3 months before travel but some were released early - 19 Euros for Paris-Grenoble.
