ANy reason why you are spending 2 days on Jost?
You could also rejig your itinerary and stay in Leverick for the beach BBQ on a Friday. We always try to tie the Friday night BBQ and Jumbies performance into our schedule. One of the best BBQs I have ever had! Captain can worry about getting up early and getting you back to moorings base before 10AM on the sat.

The below (suggested - take it or leave it!) Itinerary does not include Anegada - If it is your first time there is enough to enjoy around Tortola and outer islands. Also only 5 days and you can save Anegada for your next trip!

How about
Monday - Cooper/Peter island - if cooper dinner/drinks, if peter dinner/drinks at Ocean's 7 beach club
Tue - Norman stay in the bight- dinner at Pirates Bight (to willy T to keep the party going!)
Wed - Jost - day at white bay dinner at Corsairs
Th - stop at Sandy Island, or Diamond Cay for lunch - Cain Garden Bay for night - taxi to Bananakeet or the D'coal Pot for dinner
Friday - Head to Leverick - rent car to baths and tour island, Friday Night Leverick BBQ
Sat - back to base

Cheers!
