Frequently Asked Questions

Does this tour go behind the scenes?

Yes! You'll visit behind-the-scenes areas during your tour.

Can my child participate without a parent or guardian?

A parent or guardian must accompany all participants under the age of 16. Minors 16 years of age or older may participate with a signed waiver from a parent or guardian. Parents or guardians accompanying children must be at least 18 years old. For example, a 17-year-old may attend a tour with a signed waiver, but their 10-year-old sibling may not accompany them without an adult.

Will I get to touch any animals?

Yes! Your sleepover tour will include a visit to Living Seashore, our interactive touchpool exhibit, where you'll be able to touch skates, jellies, horseshoe crabs and more. Please be advised that our exhibits are periodically closed for maintenance and unforeseen circumstances; if Living Seashore is scheduled to be closed during your tour, your tour guide will notify you beforehand.

What should I wear?

You'll be traveling behind the scenes, so closed-toe, non-slip shoes are required. That means no Crocs, sandals, flip-flops or high heels. We recommend wearing comfortable clothing, as you'll be traveling around the Aquarium. Sleepovers are coed; be sure to bring appropriate and comfortable sleep attire.

Is admission included with my tour?

Yes. You're free to explore the Aquarium during our regular hours before or after your sleepover.

What should I bring with me?

  • You'll be camping on the floor, so bring a sleeping bag! Sleeping pads, pillows and foam or air mattresses are optional, but due to limited space, we encourage guests not to bring air mattresses. Air mattresses larger than twin-size and cots of any size are prohibited.
  • You'll be spending the night, so bring toiletries and personal articles, such as a toothbrush, toothpaste, washcloth, facial soaps, medications and sleepwear suitable for a coed group.
  • Remember that closed-toe, non-slip shoes are required. That means no Crocs, sandals, flip-flops or high heels.
  • You may also want to bring money if you plan to visit the Aquarium's gift shop. Please note that shopping time is not included in the schedule. We recommend arriving early, or planning to re-enter the Aquarium after your sleepover is over, if your group would like to visit the gift shop.

Where should we park when we arrive, and are there any discounts available?

When you arrive for your sleepover, please plan to park at the Parkway Lockwood Place Garage (124 Market Place Baltimore, MD 21202) located directly across the street from the National Aquarium. Remember to bring your parking ticket to check in. Your sleepover guide will provide you with a chaser ticket to use upon exiting the garage with a flat rate of $8. To receive this discount, you must exit the garage prior to 12 pm following your sleepover.

If I decide to visit the Aquarium before or after my sleepover, is there a place to store my gear?

No. We will not be able to store your gear prior to your scheduled check-in time or following your sleepover, so be sure to store your gear in the car if you plan to explore the Aquarium!

Are sleepovers coed?

Yes. Our sleepovers are best described as indoor camping experiences and are open to any and all groups, so they may be coed. If your group wishes to have a private sleeping area, please let your sleepover guide know during check-in. We will do our best to accommodate the needs of each group, but we cannot guarantee that a private sleeping area will always be available.

Will there be food or snacks during the sleepover?

Yes! An evening snack will be provided, as well as a continental breakfast in the morning. If a member of your group has special dietary needs, please contact us at 410-576-8822 and someone will be in contact regarding options for you or your group.

Do you offer badges for scout groups?

All visiting scout groups receive a National Aquarium patch; however, this patch is not an official scout badge.

Is there a chaperone to child ratio for sleepovers?

Yes! We require at least one adult (18 years or older) for every seven children under the age 16.
