Tomorrow, I am headed to Everfree Northwest, a convention for fans of My Little Pony. As this is my first convention, I am quite anxious for the goings-on there. Also on the list of cons I'll go to this year is Rainfurrest.
I'm sorry I don't have much to say on the matter because of my inexperience with conventions in general, but you're more than welcome to post any relevant advice, or perhaps your own experiences as well.

I have no idea what a MLP convention would be like. But furry conventions are great. Try not to be too nervous or anything. Most people are really nice and the atmosphere is usually a ton of fun.
