For Robin and I we do one a one week (8 or 9 days), ski trip where he books holidays for it. The short trips are because we want to ski more. If we lived in Denver or somewhere similar (Robin is thinking of requesting a transfer that way if housing ever recovers), then we would just have ski passes and go every weekend. We would probably still do one ski trip away and one short trip which was our normal when we lived in Ontario and had ski passes to the local hill.
To ski here in North Carolina the weekends are insane, we've gone twice, mostly we take a slow day of his and go through the week. Weekends were insane in Ontario too but we could skip away for midweek nights, Sunday afternoon evening was usually good too and the hill was much closer.
A comfortable weekend at the North Carolina hills would cost us for accomodation for two nights (probably over $300.00 and then 70.00 each per day for ski passes) to ski 3 runs a day. We can take that 580.00+ and the gas, meal money, etc, and save that cost for two weekends and instead fly somewhere real for a nice weekend away where they don't have the same local crowds or just have so much hill the local crowds can't over whelm it.
Often places like this are actually much cheaper then the local hill and will have stay and ski packages. I never pay more the 250.00 return for a flight and usually we have at least one coupon or one of us flying on points. Robin flies quite a bit for work. We will also chose to drive north and pick a Virginia ski hill for a weekend away, but it's a long drive and a flight can take the same time. Have to agree for an easy flyweekend that SLC would work well, though I haven't done that one; the airport and ski hills are really close. A direct flight to Utah would have me actually at their ski hills faster then I can get to a Virginia ski hill.
It really is all about the quality ski time for Robin and I. I don't think there's anything else I do where I'm up and ready to head out the door when ever needed to get to the hill in time. It's the ONLY time I'm up and ready before Robin, LOL. I guess it's my drug. I don't drink, I don't smoke, it's what I want to do.
The one issue with flying for a short weekend away in the winter is you are at the mercy of the weather. We made it fine to our Whistler weekend in April, but one of the fellows coming to meet us from Toronto ran into an issue at the Calgary airport where all flights leaving it were cancelled as he landed. A kind airline employee who noted he was only away for three days took him aside and rushed him on to the one flight still leaving for Vancouver. If he had to wait for the next morning he likely would have been as well to fly home.
