I'm a budget traveller so I always bring my own towels, sheets and a ton of washcloths. A small tea boiler, Ziploc bags (gallon size), solar flashlight, candles and a big bottle of Advil and about half a dozen Bic lighters. music of course. anything that's not used up is left behind/given away. Pens! a handful of pens that disappear as quickly as they are used.
