I'd have to admit, I doubt there's a huge community of GP park goers who are clamoring for this to be open. Enthusiasts, sure, but the GP likely not so much.
That said, getting it open would accomplish a few things: more attractions open in the park, the goodwill (and publicity) of the enthusiast crowd, and it would be a symbolic gesture of a larger commitment to the park as a whole. It is a pretty big symbol of the park.
