I was there last Thanksgiving with my sons, and we did MK that day. It was crowded, but we immediately to Tomorrowland and rode Space Mtn, then did Buzz, and had a FP to Stitch. We never did FanstasyLand or the others that appeal to the younger set. I'm sure my then 7 yo would have liked it, but my 13 year would have no part of it.
