Hi, Crystal!
Thanks for stopping by and visiting with the Disney Parks Moms Panel!
You sound like someone after my own heart! I start planning our Disney vacations as soon as possible, but sometimes I get slowed down a bit when my 180-day mark hasn't arrived. It feels like time stands still during a Disney countdown!
Typically, park hours are released about 180 days out. Currently, the Disney calendar is available until the first part of April 2018. By the end of October, first of November park hours will become available for you to begin making more solid plans for each day of your vacation.
Extra Magic Hours should be released around that time as well.
Crystal, also know that times are subject to change at any time. So as your arrival dated approach be sure to check those park hours again to make sure that you and the Disney calendar are in sync!
Happy planning and enjoy your magical vacation! We'll be here to help you plan your Disney vacation if any more questions come up!
