Going to be spending about 3.5 days in LA later this month. I'd like to definitely hit up SFMM, but am torn about other parks such as Knott's, Disneyland, DCA. I'm not sure if it's worth my time at those parks versus doing more touristy things in the area. I'm assuming that if I want any chance of getting everything done at SFMM in one day, I'll need the Platinum Flash Pass?
FWIW, I'm going to be doing this solo. Is it worth going to either of the other parks in the area, other than for credits?
