Maybe, but to a certain extent. These events don't just happen because they want to throw a party. They typically happen to increase attendance and revenue during slower times of the year. I could see this happen at least yearly, but if they're gonna do it more times throughout the year, it's gonna be only if it's worth their while. They are a business after all, and you gotta get in their mindset and think: will putting on this event increase attendance and spending, more than what they would have already gotten at that point in time, and will that additional revenue cover the costs of the event and leave a profit? They gotta get a good ROI from all the costs they incur in extra staff, fees from the talent, etc... Anything Potter will pretty much be a huge success, but if they're already gonna get huge crowds, say at the end of each year (for example, if that was another time to have the event), they would not want to invest in another event if they're not gonna get that considerably higher profit to justify the investment. Does that make sense?
