It's no Ritz, but for a mountain/lake town, Harrah's Tahoe has some pretty nice rooms.
I stayed midweek (Tuesday-Thursday), comp'd for my addiction to gambling with my Total Rewards card. Stateline / South Lake Tahoe is a fairly easy one hour(ish) drive from the Reno-Tahoe airport.
The location of Harrah's is excellent - amongst the 4 hotel/casinos and quick walking distance to the gondolas & resort area of Heavenly. Bars, restaurants, skiing, bicycling, hiking, and even beaches beckon you from your room. Oh yeah, gambling too.
The rooms here are pretty big. Mine was an executive king. Most of their rooms are the same size - just different furnishings. Rooms also have 2 bathrooms - 1 is a 3-piece with shower stall, the other is 4-piece with tub/shower combo. Being solo, it was wasted space. I imagine the extra bathroom would be great for couples and especially for small families or groups of friends.
On a suggestion, I asked for a room on the southern/CA side. I have no idea what the view is on the other side, but where i was the view was awesome! Heavenly ski resort to the left, and Lake Tahoe to the right.
The only downsides:
1. The corridors are LOUD. Somehow the noise outside of the room is amplified inside the room. Constant banging of doors and hearing loud conversations nearly drove me mad. Had to roll up a towel to put one the floor to block the gap at the threshold.
2. The resort is showing its age (as are most of the patrons). I imagine building supplies are not abundant and pretty expensive to bring in though.
Still, it's a pretty darn good resort.
