Hello Jeananne, and welcome to planDisney! We are glad you brought your question to us.
I too have been keeping an anxious eye on the weather for my upcoming visit. If you decide to change your plans last-minute, that is not a problem at all. Guests who would like to change the date of their visit will need to cancel their existing
Disney Park Pass reservation and make a new reservation. Check the
Disney Park Pass availability calendar to be sure the theme park you wish to visit has availability on your selected date. As long as you have not yet entered a theme park on a particular date, you may cancel your existing Disney Park Pass reservation and make a new one for the same day.
I hope that helps! Please feel free to stop by planDisney again with any additional questions you may have. I'll keep my fingers crossed for better weather for both of us! I do hope you'll be able to enjoy all the
holiday happenings during your visit -- I know I'm looking forward to sampling some festive holiday treats.
Anne Marie
