Hi, Scotland can be as good as the Alps for skiing on a good day (except for the size of ski area) with blue skies, sunshine and great piste conditions, however they are sadly not looking so good this year so far. Hopefully it will improve and if so and you are able to take off without too much advance notice, I'd recommend the Cairngorms. You could fly into Inverness which would be your best Airport and stay either in Aviemore (a bit built up these days) or I would recommend Glenmore or Carrbridge (you would be better with a car though). There are so many lovely areas around there, and if you do end up unlucky with the skiing, you can still fill in your days with countless other activities, such as stunning walks around Loch Morlich and Loch an Eilean, or you can go up on the mountain to walk with real reindeer and accompany the ranger in feeding them. There are land rovers safaris, cycling, and you can still go up to the Cairngorm Mountain and take the Funicular railway to the top.
However if you want guaranteed snow conditions and good weather then Europe or the States it is
If you need help with that, I can do that, feel free to send me a message.
The following is a handy guide to the ski Centres in Scotland.
