Flight
John Wayne Airport in Orange County is definitely the closest to San Clemente (about 20 miles away). It is a smaller airport so offers limited direct flights but it is an easy uber ride from the airport to San Clemente.
Flight
San Diego offers a lot of options for flights from around the country. However, it is 60 miles from San Clemente. It is an easy, straight drive up the coast from the airport and there is also a train you can take from San Diego into San Clemente. The train is not a straight shot - bus or Uber/Taxi to the station, then a transfer in Oceanside, but is an option is you want to fly to San Diego and not rent a car. Plus a beautiful ride mostly along the Pacific Ocean.
Flight
LAX also offers a lot of flight options and is 65 miles from San Clemente. There is a Metrolink/Amtrak train from Los Angeles to San Clemente.
Flight
Long beach airport is a very small airport but they do offer some great flight options from certain places in the U.S. It is about 45 miles from San Clemente.

Travel Note
In addition to the 2 hotel blocks, there several smaller boutique hotels in the heart of San Clemente, many of them ocean front. Due to their small size they do not block rooms, and are quick to fill up, so if interested, book soon. Some recommended are: San Clemente Cove Resort Casa Tropicana Sea Horse Resort The Beachcomber The San Clemente Inn Higher end resorts in Dana Point: Monarch Beach Resort Laguna Cliffs Marriott Also many other options are available thru Airbnb or VRBO. The wedding venue is very close to the San Clemente Pier, something to keep in mind while booking your stay.
