I wore skirts, or took my pants off completely.
You get the hang of the right angle to lean at after a bit. ALWAYS carry tissues. I wash then dry with a tissue (check that the tissues can go in the toilet!) with the hose I ALWAYS start it pointing away from me, incase its a strong water pressure. Then I aim from front to back, then dry myself.
its then courtesy to rinse the toilet and floor incase of 'splashing'
If there is a bucket and scoop, try to pour it down yourself, without touching yourself with the scoop. if no scoop use your hands to scoop. then rinse well and dry with paper.
Carry aquim/hand sanitiser for before meals!!!

Where abouts are you holidaying?
