Flight
This is the best place to fly into. You could fly in to Long Beach Municipal, LAX, or San Diego International Airport if those are easier for you to get to, but travel to San Clemente will be easiest from SNA.
Travel Note
We are so grateful for anyone travelling to our wedding from out of town. Dana Point, Aliso Viejo, Mission Viejo, and San Clemente are the best cities near the venue to look for accommodations. There are many good options on AirBnB and VRBO, as well as several hotels in the area.
