I'd like to add in a couple of questions on tipping please. 10-20% is a pretty broad range. I realize that may depend on the level of service. But I would want to believe the service is pretty standard and a great time will be had. So what is the actual norm? Also, is that based off of the standard rate or the discounted rate if I am able to obtain one? I assume the tip should be paid is cash, correct? Do I pay that directly to the captain or leave it in the cabin on the last day or is it paid to the charter company? Thanks y'all!
