me and a friend want to go skiing on mont blanc and travel around the area for a couple of days.

We already have a place to stay in La Salle, near Courmayeur ( https://www.booking.com/Share-si1ppbg ).

I will be driving there - for gas and highway it should be around 65€ per way. 

Dates are between 15-19 and 21-24 but we still have to decide how many days specifically
