IIRC, Dive House is the new House Dive Op at the Casa Del Mar. I THINK that Del Mar Aquatics now operates out of El Cid La Cieba. I haven't used either of them, at least in a very, very long time. Once, a long, long time ago, I think it was 1993 or 1994, I had given up on Fantasea Divers (which is no longer even around), I was staying at El Cid, and went with Del Mar Aquatics for one day. Big, slow boat, 22 or 23 divers, they put us all in the water at one, with one DM at front and one in the rear, and drove us like a herd of cattle through the dive. I canceled further dives with them and found a different Op. But a lot can change in 22 years.
