Sleepovers at The Marine Mammal Center

Seals & Slippers: Sleep under the Stars at The Marine Mammal Center!

Experience The Marine Mammal Center like never before! Join us for a sleepover, which we call Seals & Slippers. It's a great chance to experience the Center in a small group setting after hours, all while camping out with the seals and sea lions!

In this unique program, lucky families get to camp out under the stars and take part in a variety of educational programs. The evening includes activities in our discovery classroom, a private nighttime tour of our hospital and a delicious dinner in our Commons. The parents and children even get to observe the night crew take care of the animals at the nighttime feeding!

In the morning, breakfast is served, followed by an invigorating hike down to Rodeo Lagoon and Rodeo Beach. We end the program back at the Center, where you will be able to enjoy some time in our gift store—you will receive 10% off as a special thank you—before saying goodbye. It is a truly memorable adventure for the families who take part!

Sleepovers Include:

  • Overnight stay in our outdoor courtyard
  • An event full of educational, staff-led activities
  • Observe patients' evening feeding session
  • Dinner, dessert and continental breakfast
  • Guided Hike around Rodeo Lagoon
  • 10% off in our gift store
