I have seen /16 subnets on wifi networks.  I think some are even bigger
than that.

Some of the stadium setups are insane.  2000 APs is not unusual in a
single network.  If you have 50000 people and most of them have a cell
phone and decide to connect to the network, you get a lot of devices.
No idea why people go to events with expensive tickets and then spend
so much time on social media while there.
