I've been reading and searching around and getting conflicting options about renting a car and driving ourselves to various places. Frommer books seem to really discourage it and others feel it is a great option. Most of the negatives seem to revolve around traffic and congestion within San Juan more than road conditions and bad driver habits elsewhere.
I'm fairly adventerous about driving and have driven just about everywhere in the USA and Canada. Including many narrow winding mountain roads and congested cities. So I'm exploring mostly for differences and local customs to study up on. Obviously things like speed limits being in MPH and distances in km are a local thing. Just ran into the toll roads (autopista) issues and toll booths (A for exact change and C if change needed I understand). But I can't find a chart of the tolls that are collected.
We're planning to drive to Arecibo (city) and head south to the observatory and Camuy Caves so PR-22 would be toll but how much change should we carry?
Some web sites I've found useful so far are:
www.hawaiihighways.com/Puerto-Rico-page1.html (Puerto Rico is part of Hawaii now?)
This last one cautions about bad drivers - bad how? I'm not finding many specifics as far as local quirks or customs aside from quick stops at stop lights (treat like a 4-way stop?) after 10pm. Not planning to drive at night. Any other customs to be aware of? Thanks.
