As great as W/B probably is -- a European-sized ski area in North America -- if you're a destination skier, why not cut out the middleman and go straight to the Arlberg, Chamonix, Serre-Chevalier, Monterosa or a bazillion other places in Europe? Besides the skiing, you get to stay in a real place instead of McIntrawestland -- I've already been to Tremblant, so I know what their faux villages are like (no thanks).
a) Price. The US $ is weaker than it's been in decades, and you'll feel pain paying for a trip to Europe. Our company will soon fly 30 of our dealers on a promo trip to Europe. Projected cost: $3,500 per person.
b) Snow (or lack thereof). This was one of Europe's worst snow years. According to climatologists, Europe may be without skiing in 50 years, and will have increasingly poor snow years between now and then. It'll eventually happen here too, but Global Warming is hitting them harder, and sooner.
On the other hand, if $ isn't an issue, and you'd like to see the birthplace of skiing, better to go now before it's too late.
I share you views on the faux Alps feel of McIntrawest. But, as a frequent traveler to Europe, I'd rather have faux than freezing. I find heating systems in those "quaint" old buildings to be fit for Vikings.
