Comfort items you can't leave home without?

[Iluvpluto2]

I can never leave my home without my chapstick. I keep it in my pocket everywhere I go when I'm at Disney. Also, I need my pillow and breath mints.

I have a question for everyone who wears flips flops or sandals. Are they really more comfortable than tennis shoes. I'd like to try it sometime, but I'm afraid they would eventually hurt (especially the flip flops) or I'd keep walking out of them or something. Thanks for any info!!
