^ First, I only went on twister once back in 1999 and never returned, so I cannot remember any of the interior.
As it was told to me, everythingin this new attraction is front to back. The first quarter is the fancy queue. The last three quarters are divided into two theaters, the first facing into USF, the other facing IOA, so they are back of house to back of house.
I was told the extended queue remains mostly the same, but I was also told that they were going to try for a no-queue model. When I asked why the extended queue remains, I basically got a shoulder shrug.
BTW, the final load hold area is somewhere down the right side of the two theaters.
Hope this helps (and that I remembered it correctly).
