I've been in Nov, Dec, May, and Oct, and I've never lined up that early to get into Fantasmic. Usually 30 (in Dec) to maybe 60 (in May & Oct) minutes before hand. We've always gotten a good seat. Of course, I prefer to be a little closer to the top so we don't feel the water spray on a cool night and so we can get out a little quicker. I also usually grab the kids a snack (or dinner) to eat while we wait - that helps kill time. And there's usually something going on down front to entertain. That's JMO, 90 minutes may be needed at times (like summer months?), but we've never had a problem.
