Flight
Sacramento is the closest (45 mins) and most prefered airport to fly into. There are plenty of car rentals located at the airport and no tolls between the hotel and wedding venue. Other airport options are San Francisco (SFO) and Oakland. Both are a lot busier airports the Sacramento and will require tolls to and from the wedding venue however you may be able to find a direct flight and/or better deal.

For the Marriott people this will be the closest location to the venue.

For those that prefer the Hilton points, this will be your closest option to the venue.
