It's been some time since I've been but honestly - Turks is all about the water/beach. Short of going to an all inclusive, you go there to relax. It's why even though I got engaged there and have gone solo for R&R time, on a family vacation, we tend to go to other islands. So please enjoy the magnificent views and water there for all of us!!!!
Our favorite family destination to mix things up was actually St. Lucia (volcanos) and BVI (sailing) for what it's worth. Obviously, PR fits the bill for activities too
