I think there is more benches there then there are trash cans in the entire park lol.
Even if they didn't take out the grass for a new coaster/ride, I'd much rather have grass under a ride than asphalt. It would keep the area cooler. Whatever they put in, it would be nice if the cue line had a roof to protect from the sun.
True, it does look there are, though, I'm sure you might of seen by now, but most of the benches have been moved, there still are a few around the Invertigo area, but not the long chain of them as there was.
It's happened to me too a few times, they ask first if it's gone or if I know what's going to replace Invertigo, of course I, like many others don't know. Firefall is the other one, some have asked if it is going to be removed too because of it's missing gondola.
