2. HOT all the time - Wire red and yellow to batt and use radio switch as ON/OFF. Cons: May drain batt if left on and kids will mess with it. Pros: Won't skip a beat.
3. Rocker ACC switch - Same as #2 above except you have a rocker switch with indicator light.
I'm leaning towards #1 since it is foolproof and there will be kids in the mix.
I have mine run like option 2. Prefer it that way. I do have a perko switch that shuts everything down except my auto bilge.
How will the kids mess with it?
When I was a child, I used to talk as a child, think as a child, reason as a child; when I became a man, I put aside childish things.
