Travel Note
San Diego International Airport is the most convenient airport to use for the wedding weekend. From there you can get a rental car, Uber, or Lyft to get to a hotel. LAX may offer direct flights, but the airport is much busier and it can take 2.5 hrs to drive to San Diego depending on traffic. I wouldn't recommend LAX unless you plan to spend time in LA or stop at Disneyland on the way. Long Beach Airport is also an option if you plan to stop at Disneyland, however it is unlikely to get a direct flight.
Hotel
The RB Inn is one of the nicer accommodations and is 20 minutes from the venue.
Hotel
Suite-style rooms good for families traveling with kids. Close to restaurants and the highway. Rooms have kitchens.
