Now what if you have both? We’ve put together a list of places with long hours for drop-in (plan on being 45 minutes later than you conservatively estimated, right?) that can accommodate both of the aforementioned phases.  And that’s all parenthood is, right? Surviving from one phase to another?

Open Hours at the California Academy of Sciences
Welcome to the Academy: the only place on the planet with an aquarium, a planetarium, a natural history museum, and a 4-story rainforest all under one roof.
