Two years ago we took an excursion to Reef Yucatan in Progreso. We did not book thru the ship, buy were offered this excursion before we left the bus that transported us from the ship to end of pier. I'm just trying to find out if this is still offered and how much it is now. I know that I can book thru the ship if necessary - but hate to pay more than I have too for the same trip! Any help out there?
