If this helps anyone else I spoke with both dolphin and dohms about an after hours taxi around 5:30, they quoted me prices around $125 each + either 25 or 40 dollars entry fee to BVI to road town, $94 + fee to west end. That was two/three days ago before I bought the tickets. I finally found one landing at 1pm on sat so we're good to take the ferry and can avoid the custom taxi rate, but yeah. That's what I was told via phone by the taxi operators, they must have figured a way around the rules or perhaps that isn't in effect yet? Anyway - FYI
