Four Seasons Resort, Aviara is a wonderful place. The villas are beautiful, and they include daily maid service. If you want to go in August, good luck. That is racing season in Del Mar, (just down the coast) and Aviara is often booked with their own owners.
That said, if you are lucky enough to get a reservation, you won't regret it. There is a lot to do in the area, the resort is beautiful, and it is also very child friendly. Give it a try, but try to book NOW!
