If I significantly enjoy the one I went to, resolves to that one.
Otherwise, I will ask around to hear what happened at the other two, and resolve to whichever of those two it sounds like I would have liked the most.
If I move around between multiple, I'll resolve to multiple if they were about equally good, or to just one if it was significantly better than the others.
I do not commit to attend the one with the highest probability, but will factor it into my decision. Comments with information will likely sway me more strongly.
@asmith Not really, the nearest to where I live is about 400 km away. Though the uniqueness criterion is still a good one, both Puzzled Pint and ACX meetups I can at least potentially attend in the future.
Of course there might be more Metagames, but going to the first of something is always more special.
