Scrub is essentially a Marriott with a marina. And pool. Really the only thing special about it is the ability to use said pool. Personally if on a charter I would want to squeeze every bit of time into exploring the area and beaches. I don’t see the Baths on your list (maybe I missed something in one of the posts). A second day in Virgin Gorda with time at the baths or a trip to Necker with Gumpton would be much preferred by every crew I have taken out (adults and kids included). Guana Island is also a great option unless you require dining at an establishment instead of on board. Stunning there. We skip Cooper now as well.
