For popular tracks the trick used to be to arrive for an earlier less popular talk. Does not really work anymore, past 10 you'll probably never enter the PG or Rust tracks unless you spend more than 1 hour waiting outside.

Good news is streaming is really good so a fallback is to stay at the cafetaria and just stream. Lightning rooms usually have some space too :).

Edit: disclaimer my last Fosdem was in 2020 ^^
