- Poster in poster tube if you will present a poster (note: this counts as a carry on)
- USB where your talk is stored if you are giving a talk
- Address of your hotel and the conference venue
- List of people you intend to introduce yourself to at the conference
- List of economical restaurants near the conference venue
- List of nice/expensive restaurants (for the one night you want to spoil yourself)
- List of places nearby that you want to see. In case you have some time to tour the city.
- One change of clothing for each conference day. Sometimes you can recycle some clothing (a pair of pants or a sports coat). Packing light is key! One extra change is ok, just in case, and maybe an extra pair of comfy shoes (because you will be walking a lot)
- Granola bars (to keep you going through the long days)
- Water bottle (to keep hydrated)
- Cell phone and cell phone charger to contact colleagues for lunch/dinner plans (I always forget my charger!)
