Did a couple of dives with Jose at Akumal dive adventures while my wife took a resort course with Shayla. A 2 tank dive is $62 usd and they go to reefs that are a 5 to 10 minute boat ride from their facility. They have a swimming pool on site for the resort course and my wife thought Shayla was a great instructor. Excellant facility with friendly professional staff and great prices. I would recommend it to everyone and will go dive with them when we return to Akumal.
The more dives you book, the lower the per tank price. If you do at least 10 dives the price goes down to $25/tank. Jose, Shaleh and Lupe are all great to dive with. It's a very friendly shop and I've always found it to me a bit more low key and relaxed then the other Akumal shops, but that's just my personal preference.
