This is an older hotel in need of an uplift but with little competition around, it may explain why the property just feels tired. To call it a resort and spa is questionable. We stayed in one of the cottages, which I highly recommend. It was roomy and the bathroom was renovated. But the room could have benefited from a complete renovation. Our friends stayed in the main building and had issues with their AC. The restaurant is nice and attached but service was slow on the three occasions I was there. There is a nice in-house coffee/wine/convenience shop. The fact that the property seems dated was not the issue for me. It was the hefty price we paid for the few days we stayed (with the added resort fee for a property that is clearly not a resort) and the overall slow service. The quality of the property and the service did not warrant the high rates. The cottages are worth revisiting, in my opinion, but only if the rates are reasonable or you have Marriott points to spare.

Very, very disappointed in the Lodge. After many stays the The Lodge at Sonoma has lost it's charm thanks to remodeling, refurbishing and management. We have stayed in the cottages several times over several years past with friends when doing wine tastings; we were shocked at the horrible refurb of the rooms. From lodge to lower level dorm room is the best I can describe. We did not see rooms in the hotel though the grounds were still a well kept garden. Generally the hot tub was closed and smelled like chemicals; not sure the pool would have been any better. The towels were rough enough to exfoliate an elephant and basically worn out as well. One towel rack, period.
The carpet was late cave dwelling and the room was dark; worst looking furnishing I have ever seen in an expensive resort. Guess it was dark so you would not see just how awful it looked.
We were staying on points but they charged our card anyway. Not ever going back.
