What does your 14 yo like to do? Does he/she like hiking, swimming, putt putt, frisbee golf, or will strong internet/WiFi be more of what they want. Are you looking for somewhere you can send him off and you go your own way? Another way to look at this is where do you want to go that you and the kid can do something together, places you want the kid to experience.
Perhaps you could look at places near Charleston with a trip to Patriots Point, Fort Sumter or Fort Moultrie, several plantations that are beautiful. Of course with this virus thing going on, not sure what is open or what restrictions they have.
