It's like comparing apples with oranges. We really like the DBV for the convenient location. Perfect for snorkeling the house reef and no need for calling a buggy.
The RWV however is amazing. Obviously this is our first stay in a WV so we don't have anything to compare with. We are happy with the sunset view from 417, facing Rangali island with the attacking birds protecting their nests between Vilu and the WV's currently.
