We just returned from a trip where we parked at the LAX Marriott while away. Historically, we have done one way car rentals from our home to LAX. However, that price has increased so we were looking for alternatives. A friend had a good experience parking at the LAX Marriott and mentioned it to me. For a stay of 10 days or less, the price was comparable to our one way car rentals and the convenience was much greater.

You need to make an advanced booking. You can choose self or valet parking. We went for valet parking. Valet is $14 per day plus 10% tax. Self parking is $12 per day plus 10% tax. We drove to the front of the hotel and the valet took our bags over to the line to wait for the airport shuttle. This is the only downside. The hotel's shuttle only goes every half hour. We hit it just after a prior shuttle had left both coming and going. On our return, we texted our tag number to the phone number we were given. Our car was in front of the hotel on our return. We paid at the parking kiosk, went inside and bought a Starbucks, and were on our way.
We got points for the pre-tax parking charge of 10 points/dollar.
