Pros and cons of cons

So I have a decision to make…and it’s kind of a tough one.
There’s this convention, see. Tucson Comic Con. I wrote a sci-fi novel. Sci-fi and comic cons go together like peas and carrots. Or something. Point is, it would be a great opportunity to promote myself as an Arizona author with a new publication. The fee for a table isn’t unreasonable, and I’d have time to buy up a small stockpile of books to sign/sell at the con.
Buuuuuuuut…..The same weekend is also Coronation for the next King and Queen of our SCA Kingdom-slash-stepping down of my husband’s friend from current King to Duke.
Fuck. My. Life.
I want to be there to support my husband’s friend and my chosen family, but I also want to be able to be visibly there to promote my book at a medium-sized convention.
What do I do?
My husband was initially on-board with the con thing, but when he found out it was the same weekend as Coronation it was all nope, can’t do it. But I want to. I need to talk to him, I guess. I just feel like a jerk for wanting to.
We don’t have to do everything together. We can split the weekend–but it would be kind of a bummer not to have him there.
I’ll think it over. Who knows? I might not even get a booth. It might end up being a moot point.
But it would be freakin’ awesome to be able to do the con…..
I’ll talk with my husband. See what his thoughts are. I know he won’t be happy, but maybe we can compromise.
