I've downloaded the app on my iphone and tried to create an account but keep getting this message 'We are sorry, we are unable to create your MDX account at this time. Please try again later or call (407)939-4357 for assistance' Its only 2 weeks till we travel and i really want to book some fast passes but been trying this for 3 days nw and still the same message. I've also tried on both my laptops. Any ideas?
