Tropical Night Stay

It's the kind of thing you might have dreamed about as a child: every year, Chiba's Kamogawa Aquarium allows a small group of people to stay there all night, taking a behind-the-scenes tour of the facilities and having an evening meal before bedding down in front of a floor-to-ceiling fishtank. The 'Tropical Night Stay' will be held on each night from March 23-25, and again on April 2 and 3, with places limited to 60 people each time; call 04 7093 4803 (Japanese only) for reservations. Oh, and don't forget to bring a sleeping bag.
