Actually it's pretty much neither.
It has the largest capacity of any of the theme parks, and only closed once, when the person in charge freaked out on New Year's Eve 1999 - 2000.
Of course that was the year that Michael Eisner was staying at the Yacht Club, and HE freaked out when he saw resort guests being turned away at the International Gateway.
I'm sure that they'll be REALLY careful about that from now on.
I hope that this helps.........
