I usually think when people make these threads they are just showing off their holiday plans, so sorry to them people because I need help now too

Me and the lady are going to California for three weeks in June. We are flying to LA which will be our base city then do San Diego for 4/5 days, San Francisco for 4/5, Santa Rosa for a day (Mainly just for a Brewery I want to visit) and Vegas for 3 days. Odd few days in between will be in LA to break up the travel.
We was going to hire a car but we found hotels are as much as 60% cheaper when booked with bus travel of $25 a trip so it's a no brainer.
We have been to LA and Vegas before so we kinda know what we'll do there, but if there is anything we NEED to do, please say.
Never been to San Diego or SF so any suggestions would be appreciated! Obvious touristy attractions already being considered, just really looking for any 'hidden gems'
Cheers
