Din hoses?

[buddhasummer]

Not all the lp hoses are the same!! I still have couple of them with 1/2" fitting for my old Apeks regs(DST and FSR).

True, my older 1998 Aqualung Cousteau also had a 1/2" Lp port. I ended up using an adaptor as the 1/2" were hard to find.

Keep in mind here that there are two different kind of adapters, one for the tank that is a small insert commonly called a doughnut which converts a tank valve from DIN to yoke. The other screws onto your first stage and adapts a DIN to fit on a 200 tank valve. The adapter which fits on your first stage is probably more practical for taking to an island as it makes your reg fit either tank and has one less o-ring to deal with as the first stage adapter only uses the one already on the first stage. It is also easier to use with no tools and you have a less chance of forgetting it in a valve when you return the tank.

For that reason, I don't tend to think of the DIN insert as an "adapter" in the context of the issue of whether DIN rental tanks are common where one wants to dive--a Caribbean island in the case of the original question here. Is a diver really going to bring along a DIN insert and install it (with the requisite hex key tool) in the dive op's DIN tank on a boat before hooking up his yoke reg, then remove it during the surface interval and install it on another tank, etc.? It would be so easy to forget to remove it and take it with you when you leave the boat. And never mind the helpful DMs who want to switch your rig to a fresh tank. So in my mind, the insert is more like a "converter" (to be left on or off for some time) than an "adapter." It's not a good solution to the question asked here. Besides, I think the OP is trying to confirm a suspicion that there are few places in the Caribbean where DIN tanks are prevalent, so the question would be about adapting a yoke valve tank to DIN reg, not the other way around.
