I agree with 2-3 at the most at Disney and also with 2 at most in LA.

For many, the absolute highlight of a West Coast trip is a drive on the PCH with all the awesome sights that this entails.

I went 2 years back and the part of the PCH that I most wanted to see (Carmel to San
Simeon) was closed. I will be returning at Easter 2020 in order to specifically drive that part of the route.

I would not consider a W Coast trip without a car as it is not simply about travelling City to City. I am more than comfortable using AMTRAC when it suits.. but not in California.

I think you need to read some trip reports and formulate a plan.
Mine is ‘California N to South at Easter’. As it is all on one thread, it may give you a running start of things to do. Afterwards it would be down to researching other ‘one day, one thread’‘ reports that cover various attractions in far more detail.

Hope it helps.
