Long ago the British Virgin Islands decided they want visitors to use their airport and their taxis. One could certainly make some safety and regulatory claims. The reality is closer to local taxes, revenue, jobs, and politics.

The best solution would be a 1st class tourist ferry operation at STT taking everyone, everywhere. There are politicians and businesses on both side of the border that do not want that to happen. My two cents either use EIS or charter from St. Thomas. We have done both with equal success. In most cases you will lose two nights of beach bar time with the St. Thomas start and stop.
