Actually, Disneyland's Hub has been working much better with crowd control since this summer than it has in many years. Paint the Night has forced them into keeping the east side of the street around the Hub open, so they have been using the "alternate low attendance" crowd control plan for fireworks since Forever came online. The allow guest to sit all the way to the front of the forecourt at the ropes so the entire northern side of the Hub is fireworks viewing. This leaves the east/west path through the middle of the Hub open for cross walks, so as long as there is not a parade, then it's a straight shot from Frontierland>Tomorrowland. Cast Members are pleasantly surprised on how well it's been working. I know that getting around the park at night this summer on my trip was much easier than it ever has been. Also, Disneyland's bypass is not hideous. It's a pathway that is lined with attraction posters with a few planters and overhead trellis work that allows no viewing angles into truly hideous backstage areas. Their bypass works much better from a Show perspective than Orlando's which allows many un-Disney sights and smells to be had. My last trips through Orlando's bypass in June and January still had dumpsters on offer.
In Anaheim, not every person in the resort stands in the Hub to watch a Nightime Spectacular. With Forever, they've actually helped move even more people out of the Hub and scatter them around the park by having projections on the Rivers of America, Main Street USA, the Matterhorn, and it's a small world.
In Orlando, a huge percentage of the entire Resort flocks into the Hub each night to stare into the sky like it's manifest destiny. What Orlando needs are more compelling reasons NOT to be in the Hub each night and not more bulldozers and concrete. But, the Golden Goose needs to keep laying it's Orlando egg. It's far cheaper to do earth moving than offer creative reasons to be elsewhere. Someone get back to me when they begin to offer fireworks viewing on top of Main Street's buildings.
