This is my preferred OC airport parking location. It is close to the airport and the service is excellent. The cost is comparable to the other offsite airport locations, and may cost a little less depending on the time you make the reservation. No hassle. I recommend the Marriott!
Good facility, friendly staff. Got lost on the way to pickup location when returning to hotel from airport and saw the shuttle dropping someone off, they stopped and let me in, saved me another half hour of waiting. Will definitely park here again next time I fly out of John Wayne Airport.
