The Golden Tickets are voted on by a geographically-distributed set of what Amusement Today calls "amusement park enthusiasts", but would probably be more properly called coaster enthusiasts. These folks consider mostly "traditional" amusement parks in their votes.

Some categories make sense. While one could quibble with the steel and wooden coater award winners, they are not ridiculously wrong. Cedar Point (which happens to be my home park) may well be the best *traditional* amusement park, but there are certainly others I would consider---especially given some recent operational changes at CP.
Best kids park? Legoland may be the best park focused exclusively on kids, but it's not the first place I'd take kids even in southern california---that'd be Disneyland.
Others just make no sense at all. I've been to SFFT, and seen more than half of thier shows. And, they really are quite good. But there is no way on God's green earth that MGM-Studios should be only *fifth* on that list (tied with Cedar Point no less, which---expect for their ice skating show, which was developed at Knott's---has strictly bush-league productions.) Their big muscal number is good, but Beauty and the Beast is better. (And, Aladdin at DCA is better still.)
Disney did garner one Golden Ticket, for best nighttime show. However, I think they picked the wrong one (Illuminations) rather than the right one (Disneyland's Fantasmic!).
At the end of the day, the golden tickets are a beauty contest amongst traditional amusement parks, and serve mostly as a vehicle to generate full-page ads in the AT issue that announces the results:
