A lot of concrete replacement, some path widening, a few other necessary upgrades here and there. Not anything that I would call extremely major work, though a certain stretch of pathway is getting widened in Liberty Square that should have been widened back when they built the riverwalk for SpectroMagic back in 1991. (I may be wrong, the riverwalk might have not been built till the next year, but it was because of SpectroMagic, I know that much.)
The park is getting a sound system upgrade that will be a test for the sound system going into Shanghai Disneyland, and I hear this system is going to be stellar. I believe they even got Don Dorsey involved with the design, and that's impressive. He's probably the best audio engineer Disney uses in the entire company.
And I have no idea what the schedule will be when they open the Festival of Fantasy parade. One can only hope operations will let the dragon breathe at night. Let it be known that this parade was designed for it.
