I have always been on the side of the DIYers until this last trip to Acklins. Having a group of 6 to 9 people trapsing around on their own definitely impacted the guides from the lodges and the people "paying to fish." Granted, there's plenty of space but the local guides certainly have a system down between them and it's understood and respected.
Also, I saw signs for a couple of new "lodges," (think shack with a sign out front) but I promise you there are no additional trained guides. I know the DIY lodge that Vince represents would love to be a full service lodge if they could-they do have their own boats. It seems like everybody is trying to be a bonefish expert down there these days.
I know there's nothing that stops DIYers from fishing anywhere they like but the locals know which groups hire a guide for a couple of days and which ones don't. You're starting to see a difference in the fishing down there-it's changed over the last 6 years. Now multiply that effect by a zillion when you consider the islands that actually get a lot of visitors-Eleuthera, Exuma, and even Andros.
