GO! I was there last Saturday, at both parks, and crowds were VERY light. Walked on everything at DCA, and walked on most things at DL as well...the most we waited was maybe 10 minutes. Please go spend some of your money in the parks and have fun.
We were there on Sunday and it was empty. There was a 5 minute wait for dumbo, and everything else we walked on. I went today at lunch and walked right on space mountain.
Definately empty. Good time to go and see everything.
