Bri, if you are coming in Jan/Feb you will get $6 per day off the days that you have to pay for, not $20 or $26, which are the top level discounts that are only available for about the first and last weeks of opening, and at Lake Louise (our sister resort) when we are closed very early and very late in the season.
When I went up to the ski hill last year to buy my Louise card, I had to show my drivers licence (for proof of residency). Don’t know if they would ask for this if you had a card mailed you when you use it the first time, but it might not be worth the hassle just in case.
I have hosted LOTS of guests from the UK who have stayed up to 14 days. For an 11 day stay I would reccommend getting an 8 day pass (unless you are superfit/superkeen) (Valid 8 out of 10 or 11 days). This would leave you 3 free days for rest days/hangover days, to get a massage or go cat-skiing (poor man’s helisking!) with one of our local operators, go cross country or back-country with a guide or to take a day trip to Kimberley or Castle Mountain, or to go for a weekend up to Lake Louise. If the powder is awesome here, you can always buy an extra day or half day at the time.
Note that we will be in Peak Period pricing Feb 15-25, where tickets are $74 per day for adults.
