I managed to get one at 180, but it's not an ideal time. Been looking every day ever since. August peeps are holding tight to their ressies. Been trying for Chef Art Smith and Storybook also. Every day, several times a day.
It is a harder one to get. As recommended above, use touring plans reservation finder (free service). I’ve used it many times and have always been able to get what I was hoping for. I also put a special text tone to the number that it comes from so when the alert comes through, I know to jump on it! Good luck getting Sci-Fi! We love it there!
We had no issue getting one for 9 at 180 days. If its not appearing at the 180 day mark now, its either not loaded yet or there is a planned refurbishment/closure during your time period. Given the current environment, I'd imagine loading reservation inventory is low priority and any planned refurbishments/closures will be re-evaluated and changed accordingly. Definitely keep checking back for availability.
