NIOSA in a pandemic: The safety protocols for Fiesta's largest 2021 event The event will be somewhat smaller this year, but the organization still plans to have more than 160 food and drink booths, and nine entertainment stages. Author: Kristin Dean Updated: 8:26 AM CDT May 6, 2021 SAN ANTONIO — After being completely canceled in 2020, Fiesta 2021 is officially on the calendar in June with only a handful of events still moving forward. You will not see the Battle of Flowers Parade and the Fiesta Flambeau Parades this year, but A Night in Old San Antonio is still happening. NIOSA has been voted most popular Fiesta events several times and it was listed as the number one Fiesta event by the San Antonio Current in 2019. It's not unusual to see massive crowds flood into La Villita for the annual tradition.
