We arrive on Tuesady 7 September and stay through Sunday in a 1 bedroom at SSR. The last time we were down over labor day, that weekend was really crowded but then it slacked off and was quite nice.
We've been there twice over Labor Day (2000, and 2003). The weekend before Labor Day is actually very busy, but Labor Day istelf is DEAD! It's awesome!!!! No lines whatsoever. It was almost like you had the parks to yourself We loved it. The days after labor day were very light as well. If this means anything the wait for Dumbo in the afternoon was only 15 minutes!
