I recently stayed at the Tahoe Keys Resort in South Lake Tahoe. We loved the ability to take our dog along for the trip as some of their places allow pets. The service was incredible - very friendly.
It is different from motels as they break out charges such as housekeeping but still very economical. We are planning another trip - and this time staying in a cabin with a hot tub.

While the resort was in a nice area, I was highly disappointed by the way they hide charges. We stayed in a one-bedroom condo and we're told what our nightly rate would be and what was included. After price-comparing the condo to other places in the area and passing up the opportunity to stay at a comparable location, I discovered that there was a $50 cleaning fee and an extra booking fee added to the nightly rate. By then, the other places I had called were booked up. When we arrived, the amenities that they told us were available, like the exercise room and hot tub, came with an extra fee as well. Buyer Beware!!!!

As for our condo, it was more spacious than a hotel and it was nice to have a kitchenette. However, with the cleaning fees that they charge, I would have expected our towels to not have the disgusting stains that they did and for the plates, glasses and utensils to be clean. The bed was uncomfortable and the furnace in the place was broken so that it was 80 degrees in there and we couldn't cool off without opening the doors and windows. In hindsight, I would have made a decision to stay elsewhere.
