Management (corporate and park level) had to deal with bad decisions made by long gone owners and managers. More was spent on the park in 2005-2006 than was spent over 10 years in most parks, and both of those investments had lingering costs that weighed on the park. Yes, other parks got "more", but many of those were cheap in comparison to the costs of Kingda Ka/Golden Kingdom/El Toro/Plaza del Carnavale. And that's not counting all the money spent on the hotel that was never built among other black holes they threw money into with no return on investment. So yes, Great America and Magic Mountain got "more" with TDK, Little Dipper, X-Flight, Goliath, Joker, Maxx Force, Wrath of Rakshasa, Apocolypse, RR Express, GL First Flight, Full Throttle, SG Hot Rod Racers, Twisted Colossus, West Coast Racers, and WW Flight of Courage, but Great Adventure spent more than all those combined.
