I'm not sure it was rental apartments. I believe for a long period of it was a mom & pop type motel, not catering to divers in particular. I recall it being for sale for a long time at least a year. Unfortunately the parking is not ideal, and I get the feeling its a bare basics kind of place. I recall the place being sold and the new "Open Water Resorts" sign going up, about a year ago. I have yet to see the parking lot along Blue Heron Boulevard filled to capacity. Just from casual observation there does not seem to be a lot activity there. They call themselves a resort and have a nice website but I don't see anything about renting gear, and/or doing tank fills. Granted, Pura Vida and Force E are close but it would be ideal if they rented gear and did tank fills. Just speculation on my part, but I am guessing it would take a sizable investment to be able to do so. Or perhaps it is a zoning issue that disallows them to act as "scuba shop" as well as a "resort".I believe that it was actually rental apartments at one point.
In terms of staying there and using there dock/beach area for diving the BHB area it is not ideal because of its north east location and the prevailing currents. If an individual wants to start their dive an hour before high tide then they have to fight the incoming current to do any part of BHB other than the section north of the east span bridge. They can wait until tide slacks and work there way south or southwest to the snorkel trail, but it just isn't ideal. Also they do wait for slack tide to move south and west, if they want to get back to their entry point for an exit they have to fight the outgoing current of deteriorated visibility. If they happen to have a DPV it changes the ball game considerably, making it easy to access any place including the west span. Probably what would be the best strategy is do the northeast section, wait for slack tide to south section or snorkel trail, exit at on southeast section of beach at the park, and walk back to the resort by crossing the street and walking across the east span.
Same applies for doing night dives, no limit on when they can enter the water for a night dive, but it presents the same issue of returning. Given the park is closed at night, I doubt the Sheriff's department patrols the southeast section of beach. So even for a night dive using the southeast section of beach in the park might be a good alternative for an exit point.
So if an individual hasn't stayed there before and they haven't done BHB before, everything I have written above might come as a bit of shock to someone who thinks they are going to walk out the backdoor and dive BHB without encumberance.
