I'll keep this short. We were in WDW at the Poly from 9/10-9/14 and then in Vero Beach after that. Crowds were light. The only thing we waited for was the character meeting for Ariel (about 20 min.). We walked onto everything else (mostly in Fanstasyland, but also Space Mtn., Haunted Mansion, Splashdown Falls, etc.). We tried to hit the parks early, but sometimes didn't get there until 10:30am. The parks were all clean, and the CMs were friendly and helpful. The free dining plan was wonderful - we were never hungry. The Poly was the best! Big room with view of the quiet pool (which was really quiet). Any questions, just ask.
Enjoy your trip!
