Float plane training in California
 

I'm planning a holiday to California next year and I would like to do a bit of flying does anyone know where I could do some hours in a float plane.
I'm going to be in San Francisco then driving to LA so I'm open to suggestions as regards location.
I've got an NPPL so I can't solo but it would be nice to do a few hours, can't spend too long as the other half will complain ;)

I've Googled but not found anything relevant

Thanks for any help you can offer
