The Lodge at Sonoma (Renaissance Resort & Spa) has received good reviews on tripadvisor. We're thinking about staying there for a quick two day trip from SF. Based on the reviews, many people had reservations but then got upgrades (to the cottages) when they checked in. I assume they are all Marriott points people--which we are not. Have any of you stayed there who were not points members and gotten an upgrade? As most of the reviews talk about the cottages, I am interested to know if the standard rooms are nice or is it just the cottages that make it worth the stay?
