I've stayed at the Mountainside Inn several times now and would definitely go back. It's no 4-star hotel, but it's certainly adequate and I've always found it very convenient. Decent parking, slopeside, nice little kitchenettes, easy walk to downtown and there's a shared hot tub. It's older and definitely showing signs of its age, but it's pretty affordable and that can be hard to find in a ritzy ski town. Also, they have some nice suites. Last time we were there they upgraded my family to a 2-room suite for free and it was a lifesaver for our group with 3 young kids to corral.
