Easily.
Here's the way I'm looking at it.
Something around 7,000/7,500 there yesterday. You can guarentee everyone one of those will know at least one person who didn't go yesterday but will definitely be at the final. That takes it to about 15,000, and that's being conservative about it.
Then you start to add ex-pats and peoples families and kids who will all be going along too.
It's not long in adding up.
