What to take on a coach for 5 hours?

Maybe a blanket and a pillow (or something to use as a pillow). Maybe something to cover your eyes if you want to sleep (hat, scarf, sunglasses etc.) Food, water, sweets/mints. Last time I was on a long coach journey I bought a cheap bath pillow with suction pads on it, it was �4 from the Factory shop, I just stuck it to the window and slept :)
