It might not be the thing you are looking for. I took two of my boys (13 & 15) on a flounder gigging trip with
https://nocturnalassault.com/ Both boys love rod and reel fishing, but also loved gigging. Might be something if you want to have a good time away from the heat.
Captain James is quite good with kids. He will have one his right and one on his left spotting flounder for them saying "get it get it get it!" lol Like you I was more interested in the kids fishing, so I stood behind the 13 year old and gigged two from that position and missed a third. He expects some fish to get missed and doesn't get grumpy about it.
He usually comes home with a limit, I really dont recommend most flounder guides as the norm is to come with much less than limit. Not that limits are the be all end all but it gets pretty boring for kids to go long periods of time with no action.
I dont have experience with "Surrender at Sunrise" but I suspect he is good to and that boat is also set up well to run two people gigging.
