I'm sorry, but my butt hurts just sitting for the half hour before the show. No way I would spend half a day waiting for Fantasmic (although I love it).
They have this problem with all the shows in Tokyo. So many people would wait for the shows and parades that it became a traffic congestion problem. Now they won't let people reserve a place until about an hour before show time. They even make announcments about it. That might be a good idea for Fantasmic at DL as well.
So many people were waiting for Dreamlights that is was at least 10 rows back from the curb (and they make everyone sit). Still a heck of a lot better than queuing up all day for a night time show!
