Are reservations for the Tomorrowland desert party available at 180 days?
Yes, most of the time. There have been issues with it being slow when Wishes is not at 10 because it had to be hand loaded. There was a report on chat they were scheduling everyone at 6:00 now and you had to know what time Wishes was scheduled on your night and come an hour before that. I do not know if that report was confirmed.
Ours only came available at about 170 days we just kept ringing everyday at 12 pm
