Just competed a good stay here (as plat).
SNA applied which upgraded a standard room to a cottage room. $60 breakfast credit was given (I assume $30 per person - menu below) along with a voucher for 2 free drinks, each up to $14 (mainly 5oz wines and some cocktails).
$45 resort fee theoretically covered fitness classes, but only on Fri-Sun; travel to Sonoma Plaza; a minor wine tasting session (only two wines on offer, <1 oz pours) and bike rental. Not a great return from the fee but hard to begrudge when the standard offering was better than expected.
