These are things that I found to be either absent or hard to find.

If you take tylenol. Bring some along.
Excedrine Migraine (I could'nt find it anywhere).
It wont hurt to bring Mac and Cheese since the one I found tasted funky.
If you are used to good comforters, take some along.
Twin sized "fitted" bed sheets.Hard to find and less to chose from.
bring your Levis too:-)
hope this helps.
