It seems like the first party, Halloween and the ones over Indigenous People’s day tend to sell out fastest. I have screen shots from the sale; I will take a look.
You are welcome. You can see that it is time stamped 12:26pm, so about 3.5 hours into the general public on-sale on the first day of ticket sales (not including the MK pre-sale). So while ALL dates didn’t sell out on the first day of sales, many, many did. At the end of the first day of sales, most days were already sold out.
