1. Anything that involves the thought "what if X random situation happens"?
Tom Hanks turned out alright in Castaway, and all he had was some sick facial hair and a bloody volleyball for a best friend. Chances are, you're not going to end up on a deserted island. Or alone in the desert. Or alone in the woods. You're going on vacation, not trying out for a new edition of "Man vs. Wild".
And for the umpteenth time: Hotel staff can be your best friend. You'll be amazed at all the stuff they keep behind the desk that you'll have access to.
Stop making your life more difficult than it needs to be.
