Weeelll..., in doing the digging to get to some decent parking rates around/near LAX in our discussions today about such, if there are folks from around Southern California who a) need to drive to LAX and park for travel, b) their travels will occupy the better part of multiple days or even two weeks,, and c) are seeking to earn Marriott points, the Marriott LAX offers some non-insubstantial rates for a one night stay + multi-day/week+ parking with in/out privileges. And you get the night credit + the points for the parking.
Here's two pages:
https://www.marriott.com/hotels/hote...rriott/1340315 and
https://www.marriott.com/hotels/hote...iott/OFF-22081.
The second page offers a pre-paid, non-refundable rate but that doesn't seem to constrain the number of days of parking.
FWIW.
