How funny, we were there the 5th thru the 13th too! We stayed at BWV and the hotel did not seem as busy as the last time we stayed there in Jan 04. I agree that the parks were not bad during the week, picked up close to the weekend, probably because of the MLK holiday.
However, we did run into a couple of busy EMH nights, the first one was the 6th @ Epcot-40 min wait for Soarin, the other was the 9th (I think) @ MGM, long wait for the Great Movie Ride after Fantasmic let out, then fine after that.
Have fun!
