I have someone arriving in SXM at 3:15PM on a Thursday, who needs to take a ferry out of Oyster Pond. I haven't made that drive at that time of day in many years. Does anyone have any thoughts on how long of a taxi ride that is at that time of day?

Arriving at 3:15 means maybe out at 4ish after immigration and luggage.

The bridge openings are 3 / 4 / 5 and causeway 3:45 and 5:15
So Simpson Bay will be very slow, so hopefully you can get to the causeway without the bridge back up extending that far and go thru Cole Bay which will also be busy
Regardless I don't think 45 minutes is doable, would budget an hour for sure
Others?
