As a general yo will be fishing in federal waters and don't need a state fishing license. There is nothing like watching the eyes light up on a youngster when they get a fighting kingfish or thier first shark. 8 to 11 year olds seem to enjoy it the most.
Children actually take a lot more attention than adults.
They have to be watched constantly. A little caution goes a long way. I find people who do the above and take Draminine never seem to have a problem. The boat is yours for the day and we are here to serve you. But I tend to discourage it.
