If you are going to the Dillon/Frisco area and learning then I would drive an hour away for the first day or two and go to
Ski Cooper (yes Ski Cooper, not Copper) in Leadville, CO to learn to ski. The tickets are very much cheaper and the mountain is less crowded and great for beginners. It is no where near being the largest mountain, but it is easy for beginners. Then you can do Keystone, Copper, Breck or wherever once you've learned the basics.
We stay in Frisco and do this for the people that come with us if they are new to skiing. It really helps transition people to the mountain.
