Whistler has a great bus system, easy to get about and most condos not far from the route. IF you take a look at the accomodation maps and the bus route map you can find something that fits in your budgethttp://ww1.whistlerblackcomb.com/acc.../map/index.htmhttp://www.busonline.ca/regions/whi/....cfm?region=0&
I have a place in the Legends in Creekside. Can't get any closer to the Creekside gondola, but it's not the main village. Skiing Blackcomb requires either a bus ride or going up the gondola, ski down to whistler village, then up blackcomb via excalibur gondola.
One thing to look at as well is proximity to one of the grocery stores in Whistler. There's on in Marketplace, in the main village, in creekside, and nesters.
The best place I stayed before buying my place was the Gables. Its just across the road from blackcomb base, very convenient, but also private. I've also stayed at stoney creek, chateau whistler, glacier lodge, delta, and a few more that I can't remember.
Extremely Canadian is great. I've done it 5 or 6 times by now, maybe more. Great skiers and they will show you areas you would not find on your own. They will bring it up to whatever level you and the group you're with can ski at.
No experience with kids ski school, but they look like they're having fun whenever i see them on the hill. whistler kids have they're own areas at whister (mid mountain), creekside, and blackcomb)
