Be advised I have the email templates and Facebook notices lined up ... The birds are in the air ... The hammer is cocked ... I've already announced the cliche first two-thirds: "On your mark, get set ..."
Sure the Orlando one is longer, but one can debate that they even out since some people prefer a longer show, while others think it's a tighter show in Anaheim. But I'd say the reliance on live action at Anaheim vs. the video of Orlando makes me choose Anaheim for sure.
Other than that, the shows are nearly identical. So my vote goes to Anaheim... but if this was about the Haunted Mansion in both parks... Orlaaaandoooooo... or Star Tours... or the Monorail...
