Peter,
There is a lot to do in Napa and Sonoma. Downtown Sonoma has an old fashioned square with a lot of independent shops, galleries and restaurants. Here's a [link=http://www.sonomacounty.com/things-to-do]link[/link] for things to do in Sonoma.

In Napa they have the [link=http://www.oxbowpublicmarket.com/]Oxbow[/link] Market that has a great farmers market on Saturdays and many specialty food stores. Here's a [link=http://napavalley.com/?gclid=CMn6pMi817YCFegWMgodunMA7w]link[/link] to travel planning in Napa. There are some nice Spas in both towns that she could visit too. You could definitely bribe..errr...talk her into coming.
