Surf Holiday Cali Help

Hi, I’m going to Cali for holiday in about 6 weeks and need some help. (from Europe btw) I'm planning on surfing for about 7 days, so buying a cheap used board and a worn out wetsuit (I'm a student. so my budget is pretty limited
) is my best option (planning on selling before leaving the US).
First question - would I be able to handle a fish/hybrid, if my only exp. is on a longboard? I've surfed in Portugal and French Polynesia and I think it went pretty well (I'm an alpine skier + baseball player), considering how little experience I had.
Second question - any good "beginner" spots from SF to LA, where I won't get slammed for being kinda new to this. I will travel by car and mostly sleep in a tent, my only goals are to surf and enjoy Cali.
Thanks for any help and tips!
btw what is a must see/visit near the coast?
