Themons, I don't totally agree with your post.
True, the shore dives in the San Nicolas area where Jads is located are, depending on the weather, mostly for experienced divers. But JADS does most of its boat dives on the reef on the South coast of the island. These dives are suitable for all divers. Jads' dive boat is moored right behind the airport which is just outside of Oranjestad and pretty close to where the cruise ships come in. So I don't see your point that there are long drives, if you choose to do boat dives. Plus, the long drives that Themons is talking about if you choose to go all the way to San Nicolas for shore dives, are about 30 minutes, and in my book, not that long.
And another point that I have made many times already on this board: the diving near the hotel area is awful compared to the diving elsewhere around the island. The Antilla is a good dive, but only if you can get there first thing in the morning, before the masses arrive. So my advice is to avoid this area and choose to dive on the South coast of Aruba. And if you're up for something trully special (and you're diving skills are up to it), dare to do the Baby Beach shore dive and other sites around this area. After this dive, you'll feel ripped off if a dive operator ever again takes you to the Pedernales.
Anyway, have fun and dive safely!
