I personally don't think that Fantasmic is worth a 30 minute wait, let alone a 45 or 60 minute wait and definitely not a 90 minute wait!
I can't beleive they scrapped the Dining Package entrance and the reserved seating. If you book the dining package, you should be able to turn up 15 minutes (30 max) before and get a seat otherwise what's the point of booking the package?
I'd rather stroll around
MK or Epcot and catch Wishes or IllumiNations from wherever I happen to be at the time.
