It is probably best not to go on holiday to a country where you wouldn't want to be incarcerated.
Yea, I know most of us plan not to get arrested when we are on vacation, but innocents can be arrested (ie. Bridget Jones - The Edge of Reason) and you might get really stupid and decide to take some drugs with you (ie. Midnight Express) or just be a bit forgetful and forget to dump or use your stash before heading to the airport (um, that never happened to anyone I know).
I suppose this several limits options for holidays but seriously, I wouldn't want to be falsely arrested in a place like Indonesia. Or China. Or Afghanistan. You get my point.
