Need help figuring out travel plan for 6/27

Hi! I’m not sure if this is the right place to post this (please lmk if there’s a better sub for this) (Also for extra info, I’m autistic and having a plan like this is very helpful for me)

I’m going to be traveling from San Jose Diridon to Dolores Park and back this Saturday, and I need some advice on the most cost efficient way to buy my tickets.

I’ll probably be taking the Caltrain to 22 street and then the 55 bus to the park on my way there, and then the 48 bus and Caltrain on my way back. I’m not planning on making any other stops.

Should I buy the Caltrain day pass? Or the MUNI day pass? (or both??) Or should I just fill up a clipper card and pay individually for each trip/transfer?
