steve, your post actually was more than just pointing it out...
you gave some narritave about how because of this policy you use other operations.
the further south you go the longer the dive season becomes.
I have about 100 NC coastal dives which is about the same as my Florida total. Every businessman has to go with the business model that they can work best with. I tend to have a very flexible schedule but one that keeps flexing. It does not matter if it is a hotel room or a dive trip. I cannot afford to get locked in several months ahead but I do like to make reservations that I think are reasonable and fit my diving style which leans to the mellow side.
I dive the Keys because I like shallow reef dives and tropical fish too and we do not have shallow reef dives in NC. We do have nice offshore ledges which I like to dive as much as the wrecks. The NC vs FL decision for me is strictly about personal schedules and family commitments.
My narrative was intended to be more about NC options. Fortunately in NC we have several quality options.
In choosing my NC op I look at op quality, trip cancellation policy, intended dive site, car ride to boat, length of boat ride, amount of shade. (I have already had a couple of skin baddies removed from my old hide so having shade on the ride out and back is important to me when I can get it.) among other factors.
