Maybe work is indeed underway! :)
I've kind of got used to the fact that it's going now and am excited about the new addition.
It's shouldn't take that long to refurbish. Asimple change of film and I gues the ride preshow will take place in the Simpsons Garage. The main work would be to the Queue line theming (unless the take some tips from Alton :P )
OH that is of course if it will be a Simpsons attraction, I've not seen any confirmation of that yet. You see any confirmation while on hols Adam? Maybe some signage?
Ooo, exciting! A Simpsons ride... it's about time!
And at a Universal Park, should be a fantastic ride :D.
