Yes you can go anywhere in the portes du Soleil, provided you buy a Pds lift pass and the linking run/piste is open.
a Chatel only pass will get you down into one or two Swiss resorts, can’t remember if Morgins but ask when you buy your pass, I think at least the first Swiss resort down from Super Chatel.
There are more drag lifts both button and t bars over that way if you don’t like doing them on a board but they’re not that vicious.
If you buy a Pds pass you could go all the way to Les Gets if you’re prepared for a 5 min walk or catch mini train across Morzine.
