If I were to guess, they're probably still trying to figure out the complexities of how they can work with COVID at play.
For example, if the event had to shut down mid-season, how should they offer money back to people who never used it, or used it once, used it twice, versus someone who used it 10 times, or someone who literally went every single night. In addition, someone who bought it early like now, or someone who bought it mid-season, or someone who got it the last week. Probably a lot of politics and legalities involved.
