Does Aruba have dozens of standardized dive site markers all up and down its coast the way Bonaire does? I haven't been to Aruba, but Curacao did not seem to have markers--or at least not nearly as many as Bonaire--or a convenient coastal road system to access a large number of dive sites. On Bonaire, you look through a map of dive sites to find one that appeals to you, drive up or down the road passing dive site after dive site until you find the one you want, pull off to the side, gear up, and go in. Later in the day, drive the rental truck back to replace tanks, and repeat. The island just totally caters to divers. Aruba?
