Hello Rachel,
Thank you for visiting the Disney Parks Moms Panel with your vacation question, we are here to help.
Studio Disney 365 is scheduled for a wintery refurbishment from September 2, and re-open in mid-September, dates subject to change. As long as you didn't book your makeover during that time frame, you shouldn't have to reschedule. Guests will have to excuse the pixie dust during the closure as the Disneyland Resort prepares to bring us the new Elsa & Anna’s Boutique.
We are all waiting to hear which Frozen packages will be offered at Elsa & Anna’s Boutique. Currently at Studio Disney 365, there is not an age restriction for Guests receiving makeovers; be sure to keep checking the
Disney Parks Blog for more details.
I hope this helps and that you have a pixie-dusted time during your visit. If you have any more questions, please visit me here and let me know how I can help you plan your magical vacation.
Remember to "Let It Go" and have a Fairy Tale time at The Happiest Place on Earth!
