As a wedding officiant, I am familiar with wedding venues and ceremony details, but not so much with hotels or dinner locations.
I am familiar with Pasatiempo. If you are getting married at Peachwood's at Pasatiempo, the obvious place for your guests to stay seems to be the Inn at Pasatiempo. If you are looking for a place for your guests to stay, I am assuming you have already ruled out this inn for some reason. Other than the Inn at Pasatiempo, I am sorry to say that I am not familiar with other places to stay.
Good luck with your wedding plans. If you need an officiant for your ceremony, please let me know.
