Want to combine your sophisticated affinity for natural history with your childish love of sleepovers and Ben Stiller flics? New York City’s American Museum of Natural History has a solution for adults hankering to bunk beneath the blue whale: a Night at the Museum sleepover series, which has officially returned this spring.

2017 won’t be the first year the AMoNH lets grown-ups stay overnight in the historic museum for a night to remember. This year will be the fourth to celebrate this swanky tradition, but could be the spookiest yet considering the museum’s current Mummies exhibit. Scared of sarcophagi at night? Rest assured that if the museum’s contents were to come to life, the dinosaurs would probably get you first anyway.

As always, the grown-up iteration is classy affair for 21+ adults only. Imagine this: the night begins with a champagne reception and music by the acclaimed 12th Night Jazz Trio in the Theodore Roosevelt Memorial Hall. Guests are free to roam the floor to view dinosaurs, exotic mammals, and more by night and without the usual pack of kids pressing their noses to the glass. Though with champagne in the mix, we can’t guarantee adults won’t do the same.

A delicious buffet dinner along with wine and beer will also be enjoyed by nocturnal explorers, along with a fossil factfinder tour by flashlight and, bringing literal life to the museum, a live-animal special exhibition. After a nighttime snack, cots are provided for a gentle slumber beneath the 94-foot blue whale in the Milstein Hall of Ocean Life. In the morning, you’ll get a light breakfast snack and memories to last a lifetime.

If this sounds too good to be true, you won’t be surprised that the experience comes with a somewhat-hefty price tag. Members pay $300 for admission, non-members pay $350. For some, this may be a big ask—but if you think about all that’s included (food, drinks, museum activities, boarding), plus the fact that proceeds help support the museum, for those who can afford it the benefits are clear.

The first sleepover took place on May 5, and the next will go down on June 30th. For adventurers with disposable incomes who don’t fear the dark, purchase tickets here.
