The Grenadines are more of an open sea sailing experience when comparing it to the protected waters of the BVI. I am not sure I would want to go with a novice crew. We sailed in the BVI several times, and have switched over to the Grenadines as our preferred sailing destination due to it's beauty, lack of tourism, and the remoteness/nature of the area. Some anchorages are rolly, depending on conditions. Each time we have gone, we do have people who get sea sick, especially the first day.
