Let’s get practical. The London Stadium’s Level 1 bathrooms are a warzone during "Rule the World." If you’re in the upper tiers, you’ll face a 15-minute queue and miss the key change. Plan accordingly: go during "The Flood" (no one cares).
And spare a thought for the accessible seating (Blocks 114-116). They’re on a flat platform with brilliant sightlines, but you’re next to the main walkway. Expect a lot of happy people accidentally elbowing your head while they dance to "Shine." You’ve been warned.
