We did an independently-booked daysail from Tortola with a stop at Virgin Gorda for the Baths. www.patouche.com
This was in 11/04 while on our Zuiderdam cruise.
When booking and receiving docs from HAL, port times were 7A-6P
Embarkation day showed the schedule for the week... Tortola port times were 7A-5P (knocking off an hour in the afternoon)
Actual day we arrived after St Thomas... could start getting off ship at 8:15 (not 7A)
So in our case we had an hour knocked off of each end of the day, rushing us for a 9-4 daysail. Not sure why we arrived late from St Thomas since we had left on time.
Patouche was a great day. There are some pics of our day here: www.cmgoddard.com
(click on Cruises top left) They took a max of 16 passengers and you get 10% off by booking early. We do a daysail on each cruise so this was our daysail for this specific cruise. Walking distance from dock (go past ferry dock - maybe a 20-30 minute walk from ship depending on your pace)
St Thomas had also been shortened... 8A-midnight when booking in June, then it became 8A-11P, and then later it became 8A-9P by the time we received our docs. Also, vinow.com showed docking at Crown Bay, then embarkation day info had "tendering". Fortunately on our day at sea after HMC it was announced that we would indeed be at Crown Bay. Arriving at 8A we just barely made the 9A ferry out of Red Hook because disembarkation ran a little late even though we cleared immigration at 7:35 (you can also take the downtown ferry but we had things booked in Cruz Bay to get to as soon as we could)
