Is the studio for DOND in Media City a much bigger space than the one provided in Bristol?

Presumably depending on if they book a bigger studio. There is no reason reason for them to record it in Bristol though, the reason it was recorded there originally is because Endemol  owned the studio there, which was later sold to what I think was then known BBC Studios and Post Production. A couple of years before the end of its run it moved to The Bottle Yard which was a little more out of the city, which tends to be used more for fiction and of course was used for the revival of The Crystal Maze. AFAIK Tipping Point also still comes from the Bottle Yard after moving there some years ago.

I think Bristol was also the most convenient place for Edmonds.
