The best airports to fly into are Los Angeles International (LAX) or Hollywood Burbank (BUR). It's easy to get an Uber/Lyft at the airport, or rent a car. The hotel is a 20-30 minute drive from LAX, or 30-45 from Burbank (depending on traffic...welcome to LA!).
If renting a car, parking is available at the hotel at a discounted rate of $35 a night. Note that transportation will be provided to and from the wedding, and Uber/Lyft is readily available in Los Angeles.
