I just got back from two weeks diving with them. My family of 6 are all divers and very active while there....every second day. They are excellent, attentive and provided special equipment when asked. they have a pickup at your hotel feature that was a God send. ChiCha picked us up each time with open arms and a big Arubian smile! It made our day each time. We put in our request for sites as our family constituted a full boat as their main boat was being overhauled. Suited us perfectly. JP and Jenilee took care of us big time. As for the bottom time limits - I would say no. We stayed down until our air was expired (within reason...if you are asking to stay down till 200 psi, then who is going to say OK????) The Fingers and Isla de Ora were the best dives....healthiest reefs we saw there. Antilla was cool as were the Renaissance planes. Ernie, Anwar, ET were the divemasters and were very courtious safe and patient with all our kids.
