TravelTalkOnline Forums Travel and Vacation Forums British Virgin Islands Itineraries - how often do u make / stick to them

We've got our first bareboat BVI cruise scheduled so I've become rather obsessed with our itinerary.

For those that have cruised the BVI more than once - do you play it by ear or still keep a pretty strict itinerary?

I think I've sorted mine, but I understand that weather and other factors could cause some on the fly changes.
