Went to Whistler last year, EPIC…got a friends brother who is an instructor doing his 3rd year out there…there is nothing like it in Europe for the amount of snow you get and the size of on or off piste.
Been to about 20 European resorts, so enough to compare it with…
If you book before 1st November you get a 40% or so discount on ski pass…so you will find it expensive if you go this year…
We booked accomodation though this websites, http://www.alluradirect.com/whistler/ which has really good value properties with hot tubs etc. then booked flights independently.
Go for at least 10 days as jet lag is a hastle, means you wake up early for the first few days, so suggest getting fresh tracks which is a $15 ticket for all you can eat breakfast at the top of the mountain followed by an hour or so of just 400 or so people on the mountain. Very very highly recommended. We did every morning. One of the highlights of any ski trip.
will go back as soon as money allows. Cost around £1500 for 12 days all in. No lessons, hire or guide as the brother knew the off piste.
Also plan on Utah some day as people rate it a lot, but a fair bit of driving around pushed us towards Whistler first.
