We were there last Sept. the 27th ~ 29th. Halloween Decor was up and HM was reopen with the cute Nightmare B4 C~mas theme. Crowds weren't bad at all, however it was a little too hot for my liking, the temp. at the end of last month was lovely. Another weekend to avoid in Oct. is Utah's UEA break, my son had the Fri. Mon. Tues. prior to Halloween off last year. I just did a quick search and it looks like UEA will be 10/16~17 this year.
