We were just there... and I was like... gee.. just a couple of weeks ago I could walk this way... But there is now a wall right past the Talking Fountain near Sinbad, and a bridge right before the fountain. Not a lot of signage.
The new enterance to DD is wackadoodle for lack of a better word. You have to enter via the Jurassic park area (near some lockers and the popcorn stand), over bridge, up steep stairs, behind Flying Unicorn(which is still there, but stripped down to the metal awaiting new paint??) then into the castle....
There was a strong order of dead fish at the bridge, and we saw cast members poking around looking for the cause. We felt bad for the staff working that area that day.
Oh and the new wall threw me so much the Loss of the dragons didnt even occur to me. I was happy to see the Flying unicorn still standing, and I hope they keep that gem of a kiddie coaster around.
