My wife and I received a two day stay as a gift. If you stay, stay in a suite where you can be obnoxious, loud, rude and disrespectful of the poor saps staying in the "standard room", which is where we stayed.
It felt like the party was in our room. Had I known that the walls were made of cardboard, I would have specifically requested to stay in a room next to one that wasn't occupied. We got no sleep the first night we stayed.
The prices on site were standard (i.e. overpriced) for the Napa area. If you want a good meal, go to Calistoga or St. Helena (overpriced, but the food was better). They should state on the website that the wireless internet costs money, as do most any "services".
The staff was generally courteous, but nothing special. I've stayed in some pretty nice places, and had better treatment even when there was a humongous language barrier.
I would not use my own money to stay here, nor would I recommend that anyone else do the same.
