Long runs, huge broad runs, endless bowls, perfect groomers, extremely steep inbounds terrain, great village
reports of rain, lunchtime crowded on mountain, poor quality merchandise
We got Utah dry powder in the Alpine for 5 days, and snow 9 days in the Alpine(basically midmountain and higher, includes upper parts of treeline and beyond) and in the village.
The runs in Whistler are incredible for their length, they go on forever, lots of seriously steep and scary exposed entries over cornices real high and real steep, then endless bowls, where fresh tracks could be found 3 days post powder. Whistler is bowl-o-rama, and the long groomers are Dave Murray, and Peak to Creek and linked runs. Don't let anyone tell you different, there is no place in Utah which can match this mountain in terms of sheer vertical and distance of continuous run-lengths.
Blackcomb is generally steeper though its groomers are definitely a delight, especially off the glacier express and seventh heaven lifts. The Horstman glacier is breathtaking but then when you see Blackcomb glacier, that is the main event. There is serious inbound intimidating terrain off on the Blackcomb side, either entered by traversing high under and over "permanently closed areas ! Or bootpacking upto Spanky's ladder and then entering the so-called Gemstone bowls and chutes. Simply put, for Experts only, and almost vertical in some places, with long vertical slopes (no twin turners here, 10 jump turns and so on...), go with a terrain-savvy buddy. For the terrain park junkies there are at least three huge terrain parks, the mellow one on Whistler and then one more serious on W, and then the supposedly biggest one with the biggest jumps in the Americas if not the world(hearsay at WB) on Blackcomb.
Village is nice, convenient, caters to all types, good physical therapists (very useful in a ski area), not cheap but it is Canada, would definitely check out 3-Below, cool locals bar/restaurant.
Just tremendous trip, for the beginner, intermediates, advanced or expert.
Of course, we got lucky with the snow, but the terrain, nothing like it.
Our trip is briefly chronicled in 6 mins on vimeo, its called "An 8 year old finds Whistler-Blackcomb"... and is video number 23127304, for anyone interested.
A friend said go to WB before you die, we remain grateful we listened to that counsel.
Ski School for kids is good but because school is so big (over 1000 instructors) a bit of a luck of the draw as to finding instructors who gell with the kids and you.
