I don't think they are very active during daylight. It will start moving around when the sun goes down. Aside from some rabies issues, bats are not bad creatures. They eat loads of misquitos.
It must be nice. I just got an email from RCI that the Bahamian government is increasing the tax on cruise passengers by $14.00. That would be about an extra $81,000 coming in per Oasis class arrival. I guess they have to pay for that port. And the tax applies to passengers at Coco Cay, too.
