Do you mean the Marriott Timber Lodge in Lake Tahoe? It sits on South Lake Tahoe Blvd, so I don't think any of the units except maybe the ones on the very top floor would have a lake view.
Many would have pool, mountain, or gondola views. I have stayed in one of these, buy personally I think mountain views in the Alpine building would be nicer. However, both the Sierra and Alpine building have nice pool views.
I am speculating, though, because I always stay next door at the Grand Residence. There are a few Timber Lodge owners on here that can give you better advice, I'm betting.
