Who knew that women would be so keen to have a slumber party with manta rays and dolphins? The Ladies Night Stay promotion at Kamogawa Sea World in Chiba offers gals the chance to camp out at an aquarium while enjoying a variety of insider tours and activities. Dinner is served at Ocean restaurant, whose windows are set inside a killer whale tank, and then it’s off for a soak in the on-site onsen and an after-hours tour of backstage areas. When it’s time for lights out, visitors climb inside sleeping bags that are spread out before the aquarium’s largest tank. The deal is available March 6, 7, 13 or 14, and spots are reserved on a first-come, first-served basis.

To apply, call 047-093-4803 (Japanese). Price: ¥13,500. Minimum age: 20.
