The organizers of Miami’s Spring Break Ultra Music Festival, scheduled to take place between March 20 and 22, met with city officials on Wednesday and decided to cancel the event making it the first time in 21 years Ultra will not go ahead. The three-day event welcomes 55,000 participants daily from 100 countries.

According to the Miami Herald, concerns are rising for other large events in the area. Four cases of the virus have been confirmed in Florida, though none in the Miami area.

Several colleges and universities have also canceled international trips scheduled for students during Spring Break.

Commissioner Manolo Reyes said he agreed with the decision to postpone the Ultra Music Festival and is worried about the Calle Ocho Festival – a one day event that is mainly attended by locals.

Not all Ultra ticket holders agreed with the decision to with some saying they would still be flying to Miami for other Spring Break parties having booked flights and hotels months in advance.

“Stupid. Everyone will be in Miami regardless since everything is already booked and paid for,” one attendee wrote.

Others were angered about the confusion noting that thousands of attendees still have flights and hotels to worry about.

Though one suggested that “ Only a total moron would suggest we keep Ultra 100% on and import this virus.”
