I was there about a month ago. Some impressive stuff for sure, but I was a bit disappointed because there really weren't many trains, few that were running, and the shinkansen was being pulled around by some other kind of regular non streamlined electric locomotive, which made it looks pretty pathetic.
The huge container ship going through the fully functional lock system was surprising and amazing, as was the wunderland-esque airport. The moving automobiles, trucks, and busses were terrific.
But yes, not crowded, which is probably the problem.
