My first question is where are you going to stay? Since your question is posted here, I'm presuming an RV park. Which one is going to make a difference. For example, we recently stayed at Marin Park RV. Not kid friendly, except for the pool. It is an easy walk probable short drive with young kids, to a ferry landing. Take that over to the other side of the bay. Catch one of the tour bus type things over to Golden Gate Park. My kids loved it a few decades back. However, for my grandkids, 12 & 15, that would involve too much sitting between the 2 modes of transportation. More so probably for your grandkids. Food at the wharf should be Bubba Gumps with grandkids in tow. And you might as well forget the cable cars. The lines waiting for them during the summer are going to be very long. Without sounding like a jerk, I'd suggest your ideas of things to do with the kids are better suited for you and your wife during a longer visit during the off-season. Consider this. There are a couple of RV parks near Vacaville/Fairfax that are probably more kid friendly than most Bay Area parks. The kids would absolutely love the Jelly Belly factory tour. Or, if you are at a park on the north side of the Golden Gate, Muir Woods is a very kid friendly way to see the redwoods. South of SF, Big Basin Redwoods, if I remember correctly, has a train that takes you thru some redwoods, with an adjacent grove at a state park (park at the state park and walk to the train) with easy trails you and the kids can hike. With my grandkids, I pick one event per day that is aimed at kids and just spend the rest of the day playing card games or board games with them. Case in point, 2 years ago, we had the grandkids with us in SD. Took them on one of those amphibious duck boat rides. (The one on Frisco would bore your kids, but you'd love it!). Very cool! My grandson really looked forward to it. Back at the RV park, they had a horseshoe pit. Taught the kids how to play. Horseshoes was all my grandson wanted to do the next day when we were going to take them to the zoo. What would your grandkids want to do with you? As opposed to what do you want to do with your grandkids?
