However, whether you attend a convention as a free-range guest to attend the seminars are see your favorite actors or writers or whatever, or you get yourself a table in the dealer's room to hock your wares, there are a few tips that will help you survive.
Wear Comfortable ShoesI can't emphasize this enough. Chances are, you will be doing a lot of walking at the convention, possibly for eight hours or more, and you can't count on there being a whole lot of unoccupied places to sit (no, the floor doesn't count). Even if you are in costume, and the high-heeled boots you got look awesome with your outfit, think how comfortable they'll be towards the end of the day when you can barely walk. At Comic Con, I wore a mad scientist costume on Sunday that had a pair of really awesome looking stompy boots from Hot Topic (my #1 source for all big stompy boots). I had a great time walking around, taking pictures, getting my picture taken in turn, and buying geeky stuff. When I got home, I pried my really awesome stompy boots off my aching feet and found I had a raw spot worn in my heel.
Now, this might not be as much of an issue with those who get a dealer table, but you never know. You're not going to necessarily sit on your butt the entire time.
Stay HydratedConventions will be hot and stuffy. There will be a lot of people. You will sweat. This goes double if you're in costume, no matter how much actual skin coverage is involved. Many conventions will have food vendors, but they will be expensive. Carry a bottle of water with you and refill it in the restrooms from time to time so you don't have to go hunting for a drinking fountain before you pass out.
Be PoliteThis goes equally if you are a speaker, a bookseller, or one of the roving crowds of unwashed masses. Ask permission before you take someone's picture. Act like a freaking civilized human being. A lot of conventions have "no creeper" rules because some convention-goers have decided that a cosplayer in a skimpy costume deserves to be groped or have her zippers messed with (I wish I was kidding). That's a good way to get the snot beaten out of you by Superman, Thor, or Jayne Cobb.
There is an unstated rule that being in a Deadpool costume means you can act utterly insane and get away with it, but have some freaking standards, or the dozen or so other Deadpools will call you out on it. Acting like a jerk at a convention is a good way to get you not invited back at best, banned in the middle, and arrested on assault charges at worst.
Have FunThis is why you went to the convention in the first place, right? Walk around! Meet people! Check out the costumes! Talk to fellow writers! Attend the panels! Buy the stuff! Get out there and have a good time (within reason, see above)! Chances are you'll make some new friends/networking contacts, and you might even link up on the social media platform of your choice.
Going to a convention does take some planning and some extra endurance, but the main reason you go to one of these things is to have a good time and meet people with similar interests. Bring a camera or Smartphone and a spare charger, though--you don't want to see the Best Costume Ever towards the end of the day and realize you're phone's almost dead from the 900 other pictures you took that day.
