sorry to hear about your Dad. I would say go for somewhere reasonable in CGB and then rent a car and hit landbased places you never get to when on a boat like Smugglers Cove, Brewers Bay Josiah's, hit Bomba's, Bananakeet for dinner one night, shop in Soper's or Nanny Cay. We have circumnavigated the island by car more than once just for the heck of it.

The teens will love CGB for the hangout factor and then you can skip it on the boat rotation. Spend a few days at Anegeda when you have your own ferry to get there
Thinking CGB also because your destination on Sunday is Road Town anyway so this cuts down on the time spent ferrying around, again my thought is visit the places you would have to ferry to when you have the boat.
