I still have one FFN to burn. Based in Chicago but we will be going to SFO to see my wife's sister. Don't want to use it in SFO itself as she lives there anyways. I was thinking of making a 1.5 day trip to somewhere I can use my FFN.

Top candidates seem to be:

Highlands Inn Carmel
Hyatt Monterrey
Hyatt Lake Tahoe
Hyatt Vineyard Sonoma Valley

I have never been to any so I am open minded. I was pushing for Tahoe but my wife is not so enthusiastic because she has been there. She is voting for Highlands. I have heard Monterrey is cool but I have no idea why. I guess Sonoma Valley sounds cool but we were thinking of just doing a day trip from SFO. I'm not sure having a hotel would be of much benefit.
