Yeah, once. My SO got something but I couldn't find any designs I liked or any artists that really jumped out at me.

It's sort of the same: security is more lax (idk what it is about the Philly convention but they have the meanest security of any tat convention I've been to). Way less artists. The WW convention center is basically a high school gym. But it's much less intimidating so it might be easier to navigate if it's your first time.
