OK folks, I need your advice. I've committed to taking my niece and nephew to WDW in 2012. I took them a few years back when my niece was 5 and my nephew was only 18 months, and I promised we'd go back when my nephew was 5. He turns 5 in June. I'm trying to decide between the 3rd week of October or the 1st full week in December. My initial thought was that it would be so neat to see the world decorated for Christmas, but then again, Halloween at the world is pretty cool too. Their parents have agreed to take them out of school to go, so that's not an issue. Since I'm having trouble deciding on the dates, I thought I'd take a poll of the experts. Opinions?
