I would skip Jost, just because you are there only 5 days.

VG would be a nice day whether renting from Mahogsny or working with a taxi driver to get dropped at Savannah and at the Top of the Baths and Spring Bay.

Anegada would be a great beach day, but again with such a short itinerary we’d spend more time on Tortola and enjoy the beautiful beaches there.

If you rent a Jeep you can spend one day visiting Smuggler’s, Long Bay, CGB, and Brewers if you really want to move around a lot. CGB would be a good choice for happy hour/dinner/evening entertainment. But if you decide to just chill a bit more and want a beach closer to Scrub Long Bay, Beef Island is also beautiful. I understand cruise lines are offering excursions to LB, Beef now (ugh) so be sure to refer to the cruise ship calendars when planning a day trip there, to CGB, or to the Baths.

And a daysail with Aristocat, Kuralu, or Patouche would be an amazing day, they offer different itineraries for snorkeling the Indians or Norman Island caves, or spending time on Jost.

But do enjoy the beauty and the people of Tortola.
