At Tokyo Disneyland, the Electric Dreamlights show comes out at night, if the weather is forgiving. Luckily, no rain visited us on that day, so out came the parade. It's really difficult to find a suitable place to sit or stand, unless you camp out hours earlier.
Seriously, people camp out waiting for these parades to happen. If I've spent money for a day in a theme park, I refuse to sit down for an hour or so just to get a good spot for a parade...
