A Euro 2020 fan park in Norwich sold out for Sunday's final in under 60 seconds.
The Arena Fan Park, based near Sprowston, had sold all of its 450 seats in under one minute on Thursday morning.
Danny Banthorpe, the fan zone's event organiser, said the response was "absolutely crazy".
"Working during Covid has been a challenge, but our team has been phenomenal," he said.
Fan Park staff have adjusted their approach throughout the European Championships, altering seating and introducing new measures to make sure that spectators comply with ongoing regulations.
The organisers have used a yellow and red card system for people not listening to instructions from event staff, and have blocked the screen when people have been standing on furniture.
"I think people will be very compliant on Sunday. It's the final - nobody wants to miss such an historic event," Mr Banthorpe added.
"As we've adapted, we think that staff and spectators have had a much better experience."
The fan zone had a priority system in place for the finals.
"We wanted to look after those that have been with us throughout the Euros," he added.
