Here are some photos that show the the hub before and after the renovations, this is adapted from a thread on another board where this subject came up in referance to how much (or rather how little) seating there is in the hub nowadays so I'll include a bit of the text about that issue here too:
... as to the seating issue since the seats before were built into the planters all the way around the planters AND the planting ares were bigger , then obviously even if you put benches ALL the way around the planter there's going to be less seating now because the perimiter is smaller. So you can still get a seat you just have to stake it out sooner, and having MORE standing space (and less obstructed views) in front of the castle increases viewing space ALL DAY LONG, for stage shows, parades, and fireworks, so it really does seem like it was probably a good idea.
before the renovations (overview from upper deck of omnibus):
note that the path to the center is so narrow that no benches are put on the path to the center of the hub, there are benches built into the center of the hub around the statue of Walt, these still exist, here's another view of those (this picture includes my first wife, so It's not one I reference very often):
I also have a photo that show sometimes they DID actually put benches along that narrow path (with my current wife from our honeymoon in 2002):
there are also benches built into the exterior and interior circles of the planters around the hub, those are the ones that have gone away, here's a view that shows those older built-in benches :
Here are some pictures of the hub AFTER the renovations the benches built into the interior and exterior of the planters surrounding the hub are gone (except at the inner circle aroung the partners statue), though the other type of benches are seemingly quite abundant in these photos:
