I would have to agree with what most of the earlier replies have indicated. Disneyland is a good 45-60 minute drive from LAX or more depending on traffic conditions on the freeways. Having been a part time So cal residents for many years, I wouldn't take my chances. You would already be wasting 2-3 hours to get there and back, plus you would have to at least squeeze in 2-3 hours to be back at the airport prior to catching your connecting flight.
I would suggest going to any of the following nearby beaches/coastline instead: 1) Santa Monica 2) Venice 3) Redondo 4) Malibu 5) Marina Del Rey
