We were just there for the Pebble Beach Pro-Am. Drive along 17 mile drive, very nice drive, bring your camera. Lots of water views and nice homes, golf courses.
Drive south toward Big Sur on Hwy 1. Just south of Big Sur, there is a restaurant called Nementhe. A little pricey, but good quality food (excellent burger). The view is supposed to be fantastic 808 feet above the ocean. The day we were there it was foggy/rainy. There is a gift shop on the lower level.
Supposedly, the Monterey aquarium is great, they have discounted tickets at the Monterey Jet Center. And Carmel by the Sea is a quaint little, artsy, boutique kind of area to look around.
The folks at Monterey Jet Center were fantastic. If you can rent a sportier car, it will be more fun on US 1(we had a Mazda 626). We ended up flying some charters while we were there and didn't have as much time to see the sights.
Hope you have a great time. I was impressed by that part of California.
