Yes- my grandkids are here on the west side also and have their fall break sort of late this year. Oct.13-19. I put in for it at work 10 months ahead knowing that everyone with kids would want that week off!
We went with them and DD & SIL in Oct of 2009 (first week) and the weather was as bad as August. I'm hoping for nicer temps this time.
My DGD5 is having Disney withdrawls,

Everytime she heres the song on the radio (Good Life) she has to tell everyone that thats the song they sing in front of the Castle! When we go shopping she's asking, "Is this where the
Disney Store is?" and yesterday she was asking where the Beasts castle is because she wants to see it. She must have heard me talk about it.
I took them and their mom (DD) last Oct to DL for a surprise Mickey's Halloween Party and had a blast. Took them to stay at my mom's which is 50-60 mins from DL and told them to bring costumes because the mall was having trick or treating, and when they got up the morning of the party, I had an invitation to Mickey's Halloween Party for them.
I am being sure to teach the grandkids about the wonderful world of Disney!
