When going on a ski vacation, it can sometimes be difficult to know what to pack, but a bigger problem is that even if you know what to pack, it can be a tough problem figuring out to get everything from your home to your destination. Skis do not fit into suitcases, and the limited about of baggage that you've allowed, can be a huge problem if you're flying to the ski resort.
The simplest method to save on baggage space and weight is simply to take less. If there's a rental shop at your destination, and the rental fees for skis, boots and poles are reasonable, then, then why not rent? Provided of course that you do not mind skiing with rented equipment,
Another option is to find out if there are any ski shops in the resort area, and if they will buy used equipment. What you can then do is buy new equipment, use it, and then sell it when you're finished with it. Before you embark on this strategy, you'll want to get an estimate for how much you can sell the used equipment for, and by deducting this from the price of new equipment, you'll know how much this option will cost.
Another thing to consider is that the clothing that you'll wear on a ski vacation can be very bulky and tough to squeeze into a suitcase. Ski jackets, ski suits, Winter sweaters, etc., all take up a lot of space. There can be a way round this problem however: telephone the lodge or resort, and ask them whether they will hold a package that is going to be shipped to you, and hold it until you arrive. Most lodges and resorts will agree to this, and assuming they do, all you need to do is box up all your bulky ski clothes and ship them: you'll probably find that this costs less than paying the airline to handle excess baggage.
