Respectfully, have any of you folks gone to Fantasmic this year since they started cutting back on performances? All this advice about walking up 15-45 minutes before the show & getting seats is SOOOOO out of date. You would be extremely lucky to get standing room only space at that point. There's going to be some seriously disappointed people if they follow this advice. That's the way it was -- LAST YEAR -- when they showed Fantasmic every night of the week & two times some nights. If you happen to be going when they're only having one or two shows in a week, good luck with getting a seat if you don't show up at least 90 minutes before show time...even then, you may be shut out - earlier this year (back in very slow weeks of Jan & Feb) when there were only two shows a week there were reports of the theater being closed 45 minutes before the show due to full capacity -- no way will there be seats at 45 minutes if there's only one show in a week.
Last week, in a week that had 6 shows, the lines started forming at 6:30 for a 9:00 show. At 45 minutes before the show, the general public seats were full, the standing room only sections were full...the only seats left were handicapped and dinner package reserved seats...and that was in the pouring rain on a night that looked like they'd probably have to cancel the show. At 8:30, it was completely full -- in the pouring rain. Still raining at 9:02 and still full when they cancelled it & just did the "taste of Fantasmic" 5 minute version.
If Fantasmic is on your Must-Do list, then either get the package & show up an hour before show time...or plan on getting to the theater at least 90-120 minutes early. Buy a meal or snacks & take them into the theater with you - we saw lots of "picnics" happening in the stands before the rain started.
