Flight
I recommend flying into San Diego Airport (SAN) or (LAX) whichever is cheaper. The wedding in Temecula Valley which is an hour out from both of these airports. You will most likely need to rent a car to get from the airport to Temecula Valley.
Hotel
This is a nicer hotel. We didn’t block any dates off for this one, but if you would like to stay here, here is a cheaper link to book through Expedia!
