So I did, but it fell upon deaf ears (as I expected it would). I'm understanding in general when guests cancel, this isn't my first con and I've been attending this one in particular for years. But when this many people cancel and there are no longer any real headliners (and despite what anyone says, my belief is that given everything going on right now, most cancellations were because it's in Texas), the "too bad so sad" refund policy needs to change.
The celebrities are what you use to promote the con. When numerous celebrities cancel and you've already sold tickets for people hoping to see those celebrities, it feels really bait-and-switch-y.
The lesson I've learned this year is to never, under any circumstances, buy con tickets in advance. And I won't be ever again.
