We've done the buses on St. Marten and never had anyy problems..they ran pretty frequently and very inexpensive. Also a good way to get to know the locals. We will probably do that in Aruba too, but we're thinkind about rentin a car for a couple of days. So we'd like some info on the buses. What hours do the buses operate? Are they fixed prices depending on where you are going? What are the fares? Do they travel all over the island or on limited routes? Thanks...we leave soon!!! Can wait.
