Hello, my husband will be joining our family vacation a little late and is flying into John Wayne Airport. Is there some sort of shuttle that can get him to Harbor Blvd. at about 9pm at night?
Your husband can take the blue airport shuttle to the hotel from the airport. That's the shuttle I always take. He could call them ahead of time to make sure they'll be there.
There are lots of shuttles between John Wayne and the DL area hotels/motels. Supershuttle is the best known. I wouldn't expect that there would be any problem getting a shuttle at 9PM, but if you are worried, you can make reservations. Try www.supershuttle.com
