Although Americans are accustomed to sit down toilets and a full roll of toilet paper within arm's reach, not all countries provide the same luxuries.

South Korea, for example, is infamous for its hole-in-the-ground toilets, with complimentary toilet paper rarely seen in bathroom stalls.

To avoid a potentially messy situation, always carry a travel-sized roll of toilet paper with you. A pocket-sized box of baby wipes also offers gentle soothing support if the country's local cuisine doesn't agree with you.
