I love Llao Llao, and have stayed there 2-3 times. That said, they always give me a nice upgrade as a Leaders Club member, so I have not had the opportunity to see a bad room there (if there is one).

When Llao Llao was booked a couple years ago, I stayed at the Arelauquen Lodge (not sure of their Web site). Less expensive than Llao Llao, but also a very peaceful, relaxing, exclusive feeling place. Considerably smaller, which when I was there meant an ultra-attentive staff because they really knew each guest from the moment you checked in. I liked it a lot and would stay there again.

Finally, I really like Las Balsas, but that's down in Villa La Angostura, which is about an hour away. Beautiful lake setting for one of very few Relais & Chateaux properties in South America. Great cycling around there, incidentally, which is how I discovered it for the first time.
