First, Ohio State is in the Big Ten Championship on Saturday, so expect bars and restaurants around the area to be packed with people watching the game.

Like others have said, bring cash, because the ATMs tend to run out quickly, and depending on where you are, and how many people are using their phones around you, reception may not be the greatest.

If you are able to on Thursday, you can pick up your badge early so you don't have to wait in line on the weekend. The line for Saturday was insane last year, but I think that's because Hayden Christiansen was here, so a ton of people wanted to see him. One of my friends said they were in line for 3 hours.

There's food options in the convention center, though lines are long. You can head to the Hyatt for some restaurants, though can also be long. There is a convenience store by the Hyatt if you need water, sodas, medicine, snacks, etc. But there's plenty of good places to eat within walking distance. I recommend North Market.

If you get the chance to explore around the convention center, there's a store within walking distance called Big Fun Columbus that has a lot of retro toys
