Although that calendar shows what was
initially scheduled, I can tell you from first hand experience that
Disneyland did, in fact, have Fantasmic on 3 of the Fridays last October.
Probably due to the larger-than-usual crowds from the HalloweenTime promotion, Disneyland added showings of Fantasmic on Fridays, beginning October 13.
I was there on Friday, October 20, and did the balcony dessert buffet for the 10:30PM show. (That's right, there were 2 -- count 'em,
2 -- performances of Fantasmic that night.) Because these shows had not been on the schedule 30 days prior, I was able to get the balcony seating only a couple days before I went.
So, even though Fantasmic may not appear on the October schedule at the moment, I would not rule it out. If this year's HalloweenTime crowds match last year's -- and I think they will -- then I wouldn't be surprised to see Fantasmic back on the Friday schedule.
