How would a house work there? Similar to Disaster or would there be a tent? I know the extended queue is rather large, but I guess I just have a tough time picturing it. Either way i'd think it the 9th house would have to be back there somewhere... there's already basically 5 at the front of the park with 4 SS houses and Shrek.
Also, depending when they start work on Nintendo, the entrances to the Parade building and tent may have to be moved as has been discussed. I'd think if/when this happens, Parade entrance will go to the Hollywood parade gate and Tent entrance will start at the Simpsons gate. That's just speculation based on common sense though.
