May sure you check the Cast rates at the hotels too. There are some pretty reasonable deals. If you want to hit the Company D, it is offsite. They have a small one backstage of Main Street/Tomorrowland.
Be sure you note which days/parks your ID will get you in for. They vary at our parks. For instance, DL was closed to CMs over Saturday of President's Weekend, but not DCA.
I would definitely try to hit all of the attractions you don't find at WDW first and then go from there. Also make sure you take in all of the small performances like the Royal Street Batchelors and Dapper Dans - and don't forget the Firehouse Five plus Two. That ragtime group dates all the way back to the beginning of the park. The group was originally made up of Walt's Animators, who all liked to get together and play.
Make sure to catch Aladdin in DCA, too. It's the last year for it! Captain EO in Tomorrowland is also a limited engagement!
