I'm leaving in 9 days also.

We are staying at All Star Music (2 nights), Old Key West (5 nights) and Yacht Club(1 night).
Here's what I hear about avoiding the worst of the crowds. Avoid MK on easter weekend. I'm personally going to Typhoon Lagoon, MGM and Epcot that weekend.
Make Priority Seating reservations if you haven't already.
The Flower and Garden show starts on Apr 25th.
Davy Jones (Monkees) will be playing at the American Garden Theater in Epcot.
Show times are 4:30pm, 5:45pm, and 7:10pm on April 25-28
Make sure you see Fantasmic at MGM. The Later show (10 pm) has a lighter crowd.
If you are staying on site, Extra Magic Hour is your friend!
Most Disney Resorts have something Eastery (is that a word?) going on, on Sunday morning. Ask at the Desk when you check in.
(Easter Egg hunts, Crafts and such)
Disney extended the park hours at MK last week. So check the Website again if you haven't done it recently.
Thats all I can think of right now.
I hope it helps! I can't wait to go. NY is so cold and wet right now.
