I’ll add more later, but the key is to avoid the BVI customs offices that are used by day boats from the USVI in the mornings before 11:00 am or so. We just cleared out to go to St. John and then back in after a few days. I made the mistake of getting to the Jost office around 9:00 am to clear back in and it was a drawn out, painful experience (almost 2 hours to get through all 4 required stations). At Jost, they break for lunch - I believe - so I’d get there around 11:00 am or around 2:30 pm to 3:00 pm. The afternoon is probably optimal.
