My kid gets out of summer camp at 3pm. If we decide to show up at the parks around 4pm later this month, is there any chance that there will be fast passes available for ¡Fantasmic! that night? If not, how early should we arrive?
Agree with the "unknown" from pp, but frankly I would be hugely surprised if there were still Fantasmic fastpasses for either show available by 4 PM any day during the first 2 months minimum after it returns. The demand for an attraction that has been closed for a long period of time is always high right after it re-opens even without major changes having been made.
At the beginning there will also be 3 shows per night. The third one will be entirely standby, so that may be an option (of course it will be very late so don't know if the kids will want to stay out that late).
Make sure to get to the viewing area early. From reports, the Hungry Bear viewing area will be standing only, so if your kids are short, you don't want to end up in the back! They typically don't let people in until 30min-1hr before showtime, but lines will form before then.
