Santa Barbara - kid friendly day

Just booked a cruise for spring break next year with the grandkids. This cruise is more about them having fun since we have been there, done that already. DGS will be 11 and DGD will be 8.

I'm a planner so... We will be In Santa Barbara from 7 am to 6 pm. Now we only live an hour away from SB and we are members of the zoo. My grandkids like that zoo better than the LA one :D. So, I'm looking for ideas that are non zoo related. Personally I'd love the wine tour but I'm not sure they would LOL.

Last March we saw a Duck-type tour go by. It wasn't a Duck but it was amphibious.
