That might not be a bad thing.

There is space though for a smaller crowd if they were using the Big Mouth studio (as they did in CBB2), or indeed ditched the crowd all together in favour of something small indoors. There could also be enough room for a fairly large crowd for the launch and finale too.

And failing that, it could still be set up to use the main studio with a crowd probably outside the main studio - just needs the layout structured well enough to get the evictee from A to B.
