I leave in 13 days too!
Kind of specific to me but I always pack Ambesol or Canker sore patches. I grind my teeth at night (especially when stressed) and sometimes wake up with sores from cheek biting. Having to deal with that is a pain on a regular basis but really sucks when traveling.
I also pack a small (like 10ml) spray bottle filled with 70% alcohol. I keep it in my jacket pocket for a quick spritz before grabbing onto the high touch areas on rides. I find the residue from hand sanitizer makes my hands too slippy.
