Solitude is one of my most favorite ski areas. You get the same variety of terrain you get at Alta and Snowbird without the crowds and lift lines. Also, great snow quality and reasonable pricing.
Problems are the quality of the food in the on-mountain restaurants, and the single "john" on the main floor of the Moonbeam Lodge (This is a new complex - what were they thinking?).
Even with the few negatives, "I love Solitude" !!
