Ok, stand by for the pro-Scotland balance, from someone who has skied maybe 500 days in Scotland and 250+ across a wide range of overseas destinations: I love skiing in the Alps but have been nearly priced out of it over recent years.
There are some surprising comments on here with reference to the difference in costs between Scotland and the Alps. Despite the messages of those who would wish it otherwise, Scotland at around £1k for two folk for a week will offer a lot more for your money than the same cash spent in the Alps. if you think spending £25 a head on a simple lunch and one drink is fine, then head for the Alps. Lift passes in main resorts are around £250-300 for your six days and with even the most bargain basement last minute packages coming in at £500 a head, you're not going to drive, park, fly, ski and actually eat or drink anything for less than £1700 a couple.
Even in smaller Austrian resorts, everything costs more than you'd expect and the snow in Eastern Europe is, if anything, even less reliable than Scotland. The piste preparation is dodgy and the lifts can be even less reliable too.
Scotland is not perfect, far from it. It will however be different, in many ways. Yes, the snow can be variable and frustrating; it can also be the best in the world and the piste preparation at Glenshee for example (with two new state of the art PB600s added to the fleet in the last two years) is some of the best you will encounter anywhere. As mentioned above, recent seasons have been very good indeed, with regular dumps of powder and some simply fantastic blue sky days. Midweek and away from half-term holidays, there is virtually no queuing whatsoever and with rapid laps available, the shorter pistes are much less of an issue. Travelling between resorts is easy if you've driven up, so choosing where to ski today can be done to make the best of what is available and the changeable weather. You can take other kit with you in the car, walking or biking kit and will be driving straight to your accomodation, not sitting in a bus doing a tour of six other resort hotels before you get dropped off. Unless you live in Cornwall, the car journeys out and back to Scotland will be much quicker too as door to door from home to Alpine property will realistically take you around 12 hours.
Just remember that wind, slush, cloud and snowy days happen in the Alps too. More often than many folk would admit!
Be realistic about your choices and I hope you enjoy your trip whatever you do.
