I am also going in September and booked all my ADR's 180 days out except for Fantasmic because all the September dates were whited-out in the dinner time frame. So I call the ADR phone number and was told that all the dinner packages for September were sold out - but I was able to book a late lunch which she said would guarantee me tickets for the show. You may want to call and see if that option is still availabe - this was just about a week ago. So we will go to HS for the day - have a late lunch (1:45) and then just grab a snack before the show. I heard the show was the best in Disney and the thought of waiting in line for 90 mins. with 2 kids was a big turn-off.
