A very special gift for your grandkids (ages 6-17) is a private sleepover at the Academy of Sciences in Golden Gate Park. It’s for you, too, as adult chaperones are required. Included are personal tours of the Swamp and the Aquarium, a Planetarium show, free parking, late night snacks, story time, breakfast and next day admission to the museum. Bring sleeping bags to bed down in the African Hall, for a really true “Night at the Museum” experience. It’s on the pricey side – $119 per person for non-members.
