I had no problems with Dive house - they had AL100's for me when I needed, and second tank with Nitrox. No limit on bottom time, and we were often waiting on the boat for the divers that had gills to come up after about an hour. That added more SI time for the rest of us, but I didn't mind, and was glad that the divers with the good SAC rate were able to maximize their fun.
The greatest part of Dive house is when you are staying at FiestAmericana (how its spelled now). I think it is the best deal out there FOR THE MONEY you spend. We booked through Apple Vacations and cost my wife and I $1800.00 for nine nights including airfare from Cleveland, so deducting airfare, it cost us about $65.00 per person per day for all food and great undiluted, unlimited drinks. We also met several friends for life that have been, and will continue to stay at FA for years to come.
My wife doesn't dive, so shore diving was a huge part for me, and even though you would think I am jaded by diving the back wall of Molokini crater in Hawaii, or the Cayman walls - I really enjoyed the shore diving right in front of FA.
My wife snorkeled above me, and we dived the shore ledge, and we both enjoyed all the Xmas tree worms, the anemones, and all the usual juvi reef fish. There is a sunken mass of bridge pilings and concrete structures 20 yards offshore just south of the Money Bar (which is north of FA by less than 1/4 mile), and we took a cab up to the money bar for four bucks, jumped in drifted back to FA after hanging out at the "bridge" for a while playing with the schools of snapper and chasing a lizardfish.
The most memorable part of that dive was seeing hundreds of seargant major fish faces swimming right at you as you drew nearer to the the structure - looking for food I assume.
