We've had 9 land based trips to the BVI's and love it. It gives us the opportunity to meet more people and see more of each island. We usually spend part of the trip on Anegada and part on Tortola.
Love sitting on the deck at CRC for the first cup of coffee in the morning, or going for a long walk on the beach on Anegada. Both islands are great and are very different from each other which is what we love about the BVI.
That said we are considering mixing in a little water time on one of our next trips just to get the experience.
