Just because somebody lives by the ocean doesn't always mean there is great diving like what people think of when they hear "vacation diving".
Here in Norcal the water is cold and most of the time murky. There are sharks (so they tell me, I've never seen one) and the weather/ocean conditions can change rapidly. There are swells and waves, rocks, kelp, hazards, it's not for the weak or faint of heart. So when I hear "local diving", this is what comes to mind in my world. Even though Northern California is somewhat weathy depending on the specific community, that doesn't mean that all the certified divers in our area dive locally. In fact most probably don't. The local diving around here isn't for everybody. The ones that do dive locally tend to be the ones that are more blue collar in nature, the adventurous ones, hunters, ab divers, freedivers, younger surfer types. And there are a few attorneys and doctors I'm sure too, but by and large these people don't have a lot of disposable income but diving to them is a way of life and they get out there any chance they get on a shoe string.
So to think that our LDS's will be supported by local divers exclusively is not reality. The local divers here are the ones who bitch about the higher costs of everything in the LDS and tend to be much more self sufficient. It takes the wealthy person to come in and spend the money on first class valet service because: A) They can, and B) Don't have then time to get online, and besides they don't know where to go or what to buy. That's what they pay the dive shop and the staff to do, to set them fully up and then they pay the bill. Time and convenience to these people is way more important than saving a few coins of pocket change searching for hours online looking to save a few hundred bucks. Then of course the whole point of them coming in and getting set up is so they can jetset to somewhere warm and have a wonderful scuba vacation. They look to the dive shop to provide this information as well and sell them a trip.
So the point is, Location close to an ocean doesn't always mean automatic success. I think the future of the LDS is going to have to follow a boutique style model catering to people who want something special and can afford it. Dropping prices and thinking that more people will be attracted is misled, all that's going to do is make it hard to pay the rent and bills. It's not going to increase foot traffic or revenue.
