Been an owner of 3 units at Ridge for about 15 years. I like it a lot. We go summer and winter. Winter at the Tower units right across from the tram to the ski area and the reception building with restaurant, bar, store and other facilities, and Summer at the Emerald units which are extra large, in Cascade building. They have been doing rotating upgrading of buildings and the new decor is nice. Not luxury per Westin, Hyatt, or the better Marriotts, but still very livable and more spacious than many timeshares. The staff has a pretty friendly and homey attitude.
I have not stayed in the other buildings other than the Naegle once, but the Tower has incredible views of Carson Valley if you request the valley view side, and the Emerald units and Cascade roof deck with barbeques has a wide view with a sliver of a lake view and a hot tub.
It is great in Summer for nearby hiking, with trails right outside the property onto the Tahoe Rim Trail and to Van Sickle bi-state park, plus many other trails driveable nearby. A shuttle takes you down into town and back if you don't want to drive. It's a bit less convenient than staying in Heavenly Village for townside activities, but the view and self contained resort up top is nice too.
If you are a beach bum or just like to laze around or shop, stroll or gamble, it's not the best located, but for active outdoors people, it's tremendous.
