Both Ventana Inn and Post Ranch are possibilities--pricey,though. Also Nepenthe on Big Sur, with Deetjens, an old, quaint, inn with separate theme cabins in the redwoods and an incredible breakfast just across the road...then there are some of the old Victorian inns in Pacific Grove (sandwiched in between Monterey and Carmel.) Don't know if Esalen does weddings, but the setting is unequalled...
