Espace Olympique Savoie - skiing Trois Vallees on a Paradiski Unlimited pass

Has anyone ever tried skiing in Espace Killy or Trois Vallees on a 6/7 day Paradiski Unlimited Pass? We have skied Paradiski a few times and have the option to join some friends in Courchevel for the day - seems a great offer and saves us buying a 1 day 3V pass.

It seems that Espace Killy and Trois Vallees advertise this addtional benefit - but Paradiski seem less keen to advertise it. The only place I've seen it written is here:

They have a little section on the Espace Olympique Savoie ski area. But it says it is on a Discovery Pass which is a bit limited for us!

Any advice greatly appreciated!

Ive been to both areas and loved them both. I would just go to the 3 valleys if you have friends in Courchevel. There is enough to keep you going in the 3 valleys for a week. On the 3 valleys pass, you can ski Val Thorens, Meribel and Courchevel. Have fun , we did :)
