We were supposed to go that week last year, but had to cancel. At first everyone was saying it shouldn't be busy, but then it sounded like lots of DISers (and therefore lots of other folks, too!) would be going that week, and DL added hours and entertainment to the schedule. Sounded like it was going to be very busy after all.
I read a post from someone who'd gone then, though, and it turned out NOT to be very busy, PLUS they got the extra hours and entertainment in the park! Would be nice if that happened again for you this year.
