Hi Jenny!
So September, huh? A great time to go IMO.
The refurbs aren't up yet for that period, but count on IASW still being down (you knew that though, didn't you?)

And I bet HM will go down while you are there for the holiday installation.
New things? Well. . . they just introduced the Pixar Play Parade in DCA which took the place of Block Party Bash. It includes a lot more Pixar characters, i.e., Ratatouille, Nemo, Cars) and is a wet parade where you get squirted with water from many of the floats.
Also, Toy Story Midway Mania is opening this summer over in DCA, so that will be the newest kid on the block while you're there.
As far as a place to stay, well my recommendation is obvious. You know I'm a HoJo girl. I'm 99% sure they will have the entertainment rates available while you are there, and they are putting in a new Pirate Themed pool area with slide early this summer. It should be complete by your trip. Also, they just upgraded all their beds to Simmons pillowtops and have put microwaves in all their premium rooms! It's even better than before!! You really oughtta stay there, save some money, and have more money to spend on fun stuff in the parks!
Any more questions? Ask away. Oh, btw, I canceled my
DCL trip, cause we're going to Maui in September instead. Gawrsh, are we indecisive or what?
Edited to add: Just checked, and the Entertainment Rate IS available. You can get a premium room for $74 a night. I think that's a pretty great deal!
