Neglected?
Space in 2003
Soarin/Land Refurb in 2006
Nemo Layover in 2006/2007
Gran Fiesta in 2008
Spaceship Earth Refurb in 2008
and now Test Track's big refurb.
Are there areas that need to be improved upon? Yes, but it has not been neglected.
Refurbs should just happen to keep things in working order, which even now they are not always. So many things lacking or broken in attractions. Over time it adds up.
So 2008 is the first thing we can list before this Test Track redo, which is really needed anyway since it is a refurb. 2008. That is 4 years ago. (the attraction also needed a refurb badly then too. The ending is still not finished)
For being in the top five visited theme parks in the world, that is neglect to me.
