So excited, I have just booked the Tomorrowland Terrace Dessert party for my first choice of dates, so thanks again to Aussienic for starting the September thread and letting me know the dates were starting to appear. I had previously thought it would not be released because it's a special event until nearer the time but seems to be doing 180 days now.
However it was not as straightforward as other ADRs and I thought I'd share my experience for those of you still wanting to book. It is booking up to 15th October today. I could not get it to come up at all on either of the My Disney Experience apps (iPad and iPhone) just kept saying view menu. I was using the normal website https:/… on the iPad but it kept telling me there was no availability. Then tried on the iPhone, exact same website (I think) https:/… and it allowed me to book my date! Weird or what? However I then noticed in my booking confirmation email that we had only paid for 2 adults and it stated an infant in booking? Looked on app and it had changed my 9 year old son into an infant with a birthday of 28th March 2014??? Very bizarre! Tried to amend my booking on line (apps and website) but it would not let me so phoned Disney on 0800 169 0730 (Thanks to USLovers who had posted this free phone number on an old post, which I found by googling!) It was sorted out and I was able to pay for my son. I then had a look at my son and tried to fix his birthday. I could not amend this on the My Disney Experience website or on the iPhone app but it let me fix him on the iPad app! All very odd indeed! Anyway I guess to sum it up, if you want to book, it's worth trying a few options lol!
