You know what to pack on vacation. You know to bring your camera, spare batteries, and a bottle of water. But here are ten things you might not think of that will come in handy at a comic-con.

1. Medical tape – preventing blisters from costume shoes. (Also, repairs in a pinch)
2. Extra lanyard for your camera
3. Umbrella for outdoor lines
4. Costume-appropriate bag
5. Insoles – you’ll be walking a LOT
6. Burt’s Bees Res-Q Ointment for sunburn in case your sunscreen wears off or otherwise fails
7. Safety pins
8. Reliable writing surface (in case you have paper but not a notebook)
9. Napkins or paper towels (especially if you’re bringing your own food)
10. Extra shirt to go over tank tops to prevent sunburn or backpack friction
