Was there in 2003... crowds were awful at the parks but not consistently awful. What I mean by that is, one day you would find heavy crowds at MK but light crowds at EPCOT, and the next day you would find crowds at MK light, but heavy at EPCOT.
Funny thing is our resort, BCV, did not seem very crowded, and crowds at SAB were moderate if they existed at all. Didn't have any trouble with last minute reservations at Cape Mays either.
