Explore the Cradle of Aviation Museum by flashlight, lie down next to sharks at the Long Island Aquarium, and, for the first time, doze on the baseball field at the Long Island Ducks’ ballpark during these family and scouting sleepovers on Long Island.

The Long Island Aquarium in Riverhead has two remaining sleepovers scheduled for 2020. On April 9, it’s an Australian theme, focusing on Australian reptiles and their environment. “Unfortunately, we don’t have any koalas. I wish,” says marketing director Darlene Puntillo. And on Aug. 21, the sleepover will have a mermaid theme and will include a swim with live mermaids. “That is going to be popular,” Puntillo predicts.

Spring Into Fun

Guests will get clues that will have them exploring the museum by flashlight during this family sleepover at the Cradle of Aviation Museum in Garden City. The fun starts at 7:30 p.m., when participants arrive with sleeping bags and pillows so they can sleep underneath the airplanes. In addition to the scavenger hunt, which will have players seeking information from displays such as the Lunar Module, there will be four activity stations and a movie screening. The activity stations include making Alka-Seltzer rockets and creating trees out of paper bags and giving them tissue paper flowers. The movie is called “Backyard Wilderness” and explores salamanders, birds and other animals people see in their backyards, says Ines Jijon, bilingual educator at the museum. Pretzels and water will be shared, and at 11 p.m., it’s bedtime, Jijon says. Rise and shine at 7 a.m. for a breakfast of bagels, juice and coffee and head home at 8 a.m.

INFO: 7:30 p.m. March 20 to 8 a.m. March 21 at the Cradle of Aviation Museum, Charles Lindbergh Blvd., Garden City; $50 per person for children 5 to 12 and parent or guardian. Reservations required at 516-572-4066. For more information, visit cradleofaviation.org.
