IN regard to the latest map, the spot marked 'A' is probably directly next to the old gold mine, where the coast is very jagged, the surf is brutal, and the tides carry in and out very quickly....this is a place where anyone wants something to disappear will dump it. The pic of the road you posted leads you to the natural bridge area, but right before the entrance, it turns into a dusty, dirt road and the entire section of coastline from the gold mine to the natural bridge (collapsed in 2005ish) and natural pool are all dirt roads...and talking with many locals over the years and speaking with people who have an ear to this underground life, this is the are where Natalee was probably dumped. Although, in the days after Natalee's disappearance, the Kalpoes and Joran were seen by the marina near downtown checking the water and land near the water, so who knows where she ended up.
Finally, if it is the Renaissance Hotel, it is directly in the hub of Oranjestad, near the other high rise hotels, with no shortage of snorkel options. It is not the best snorkeling, but there are about 8,000 places to rent gear and have someone show you how to do it...also, many of these huts that rent gear, jet skiis, kayaks etc. also are drug hubs for tourists
