Local do-gooders Bean throw another all-nighter at the Shanghai Ocean Aquarium. 300rmb gets you into aquarium, a tour, a sleeping bag for when you want to curl up and a cheap Chinese breakfast the next morning. There will be music and a pillow flight, plus a chance to gawp at the fish all night in their illuminated tanks. You need to bring your own pillow, snacks, dinner and booze. Proceeds to charity.
