Not to take anything away from A-Basin, Breck, or anywhere else for that matter...BUT...
I'd definitely give Loveland consideration. It's kind of cool with Loveland Valley basically being a separate area for beginners...two great easy green runs off chair 7 for learning, and then as you start to improve, chair 3 serves up some other greens and a few blues. They also offer a 3 class pass deal...basically, you pay for 3 full day lessons, and when you've completed those, you get a free season pass. Pretty sweet deal...learn to board with instruction, then ride into May with the pass for free...and of course, that pass is good up at the Basin where the real riding is, after you've progressed beyond the Valley. Like A-Basin, free, in-close parking, a simple lodge with reasonably priced food. Things you won't find at most of the other front range areas (including Breck).
