Seems like the hardcore fans generally want quick turnover of attractions, constant ride closings, and expansions. Nice for fantasy thoughts, but those aren't practical business decisions.
Theme parks are never going to meet all of those lofty fan wants and expectations.
I always have a good laugh reading theme park PR releases whenever they mention a new attraction has the ability to be updated easily.
So far, still waiting on Toy Story Mania, Fallon, Smugglers Run to be updated.
