There are no parking meters in the village of La Jolla, nor are there parking meters in "La Jolla Village Square," which is the area along Villa La Jolla Drive where Whole Foods and Trader Joe's are located. Nor are there meters at UTC which, as ElleLaJolla pointed out, is not La Jolla, but University City. (Two different communities within the City of San Diego.)
I personally don't know of any hotels in the village that would allow you to park in their garage if you aren't a guest. There are several lots where you can pay to park, and I think bw92116 is correct - the fee is $10 a day.
One of these pay-to-park places is on the west (ocean) side of Prospect Street, near the intersection with Girard Ave. There's also paid underground parking on Fay Ave. near Silverado St. You can also pay to park in a lot on Cave Street at Ivanhoe.
Residential streets have no time limit for free parking. In commecial areas of the village, it's posted either one- or two-hour limit (and enforced). If you are going to La Jolla Shores Beach, there's a large free lot there with no time restriction.
The one- and two-hour limits in the village do not apply on Sundays, holidays, and after 6pm any day.
