I was there today. Yeah, there's still a lot unfinished... although the bathroom is open. But the swing is still behind walls, the main sign by the main entrance is still not up, the promised return of the clock outside the store is still not up, and the train/Beagle Express was not open.
And yeah, there were many size issues with adults on the new coaster. Even adults just a bit above average build were being turned away. And the ops were abysmal. We waited in a full queue, and it took about 90 minutes, with 4 minutes between dispatches (+1 more minute for the ride itself--it does make two circuits). On the plus side, the ride does have some subtle, but cute animatronic interactions: a fishing pond, spinning sign, and spinning Woodstock.
To me, the worst addition is this new kiosk to get a single fastpass for Ghostrider. It's not a bad idea, but it looks completely out of place and blocks some of the immersive rockwork at the ride entrance.
