Hurricane Gabrielle threat ??

[lanejudy]

Could a Bahamian cruise transform into a cruise to "nowhere", meaning it just circle around and comes back to PC ?

I believe it could if circumstances are such that a port stop is unsafe and there is nowhere else to go. Whether any penalty against the cruiseline would be waived for that I don't know. But extending one cruise means shortening -- or even cancelling -- another, so they try to avoid it but it does happen.
