I've been skiing JF with my 6 and 8 yo girls this season (mostly weekends and holidays) and it's been great. Other then on the beginner slopes, we've rarely seen lift lines longer then a couple of minutes (fingers crossed for this weekend...). The lodge is usually a madhouse from 11:00-1:00, but I guess it's like that in most places.
We are also looking at next years season passes, and the jr. development program. Does anyone have any experience with that program at JF?
