When I bought my tag this morning at DFB, they told us that the new $45 tags will be here at the end of this week, and they'll be pulling the $25 tags then.
They also said that the new port fee for cruise ships will be the same $45 per head, including crew, but it wont happen until the contracts are up for renegotiation. I don't know if it's true, but that's what they told me.
Also, despite what tarponchick said, conditions are good right now. Far better than my last trip in Dec of 16. Better viz, coral appears to have regrowth over dead coral, the fish are thicker than I remember from Dec of 15, which many here said was the best in a long time.
