Hotel
17 minutes away from the ceremony and reception venue. This is just a recommendation for one of the nicer while also reasonably priced hotels nearby.
Flight
This is the closest airport to the venue. It takes 24 minutes to get there from here. LAX is also a good option though, just further.
Flight
This is 44 minutes (without traffic) to the venue. Definitely a good option, particularly for international travelers.
Train
Taking the train might be a good option for some people. This is the closest station to the venue. *Protip: If you have some time before or after the wedding, it's also fun to take the Pacific Surfliner (Amtrak) up and down the California coast. Stops include: San Diego (Old Town), Oceanside, San Clemente, San Juan Capistrano, Los Angeles (Union Station -- close to Olvera Street and Chinatown), Santa Barbara, San Luis Obispo)
