really thanks for the answers...
Finally i decided to kick the trip for the next season because the plane ticket was very expensive at these dates (we are starting summer and companies blow the prices to death).
So the plan is to ride here in my winter (i already got the season pass) and then whith more time planing the NA trip (some years ago i went to tremblant but the sown quality really disapoint me)
Ok thats all, thank you very much and if you have any doubts about Chilean resorts please let me now, maybe i can help you.
Good luck with the season!
