You have to PAY CASH at the end of the TRIP.  Every other trip or excursion we took in Florida we paid with Credit Card & I tip everyone cash. Had to pay an extra 7.2% with my credit card over the phone. We had to wait in the blazing August heat while we finally got ahold of the Captain and paid an amount that he somehow figured was due. Fishing wasn’t worth it. Go a little ways out in the Gulf to buoy marker & then come back to the Bay. I was expecting more.  Saving grace was Captain Frankie whom we got to know and enjoyed a good conversation with.
