Looks like Whizzy (eww, Vail) dropped pricing info for
2017/18 season passes and epic passes.
The Epic pass is cheaper outright but the Whistler pass has some extra frills and gimmicks that the Epic pass doesn't; most notably food discounts.
Without going too in-depth with the drilldown:
Whizzy - $1290.45 incl tax CAD
Epic - $1161.50 not taxed CAD (assume
0% forex card, else $1190.54 for a market standard 2.5%)
So that's a $128 savings to
not have the extra benifits. Assuming that you don't take lessons, heli-ski, use their special hotel perks, spend money at CanSki... you would have to spend $644 on food in the resort for those savings to be realized.
I don't think I'm going to drop a G on a season pass regardless of how it's branded. 5-Day Egde card and Cypress Silver will still be my go-to mix.
