I always travel with both mini-packets of tissues and travel packages of wetwipes. I most often use the wipes. They're good as "toilet paper" in any situation AND for "washing" your hands. Another must for Thailand travel are several pairs of black low socks (I get cheap ones at Target). Put them on when removing your sandals at temple sites, take off and put in a ziplock in your purse or pack when you put your shoes back on.
