I went dec 17-21 or something and it was sweet, plenty of base, foot of pow every day. The advanced park wasnt up yet tho, it didnt bother me much at all but it wouldve been cool. However this last december had a record breaking snowfall. Usually, from what a couple whistler ppl told me, is that they typically have enough base to open from top to bottom the second week of dec., but its not definite. Basically its a gamble, the top of the hill will be open definitely (I only skied the bottom half to get back down anyhow), but Im not exactly sure about 7th heaven, harmony chair and peak chair (they could possibly be closed because of exposure, like rocks and shit, but Im not sure, thats just speculation). The prices are cheaper before like dec 22, then they get pretty steep for peak season, so thats cool. Email whis for specific details. Any more questions just post or pm me.
