Blake,
Your information is out of date. It is j$130 per leg now. So it would be j$1020 (if you have the correct change) or about us$11 vs. a us$20 point to point, door to door private ride with no changing of vehicles necessary and no additional risks involved. Since there would be 8 legs as you count them, that works out to be slightly more than about a us$1 more per leg. One dollar.... maybe you could consider it a tip...
