Hi Laura!
Congratulations on your plans to book a Walt Disney World vacation for your family!
Mickey's Not So Scary Halloween Party is a fun evening your family is sure to enjoy. Be sure to purchase your tickets for the date you plan to attend in advance. Regular Magic Your Way Park Tickets do not include admission to the special event evenings.
This year, Typhoon Lagoon will be operating up to and including October 27th and is scheduled to close for refurbishment beginning October 28th, 2012. Do keep in mind however that only one of the Disney Water Parks closes at a time for refurbishment and maintenance. Disney's Blizzard Beach will remain open while Typhoon Lagoon is closed, and vice versa. Walt Disney World posts their
Online Calendars and schedules for attraction closures and refurbishments up to 6 months in advance. If you're planning for fall of 2013, you'll want to check the calendars beginning in early May and then be able to finalize your plans.
Thanks for visiting the Moms Panel Laura.
I hope you'll visit me again soon with more great planning questions.
Wishing you a simply Magical time as you begin planning your Walt Disney World vacation!
Kirsten
