Joey, et al:
Here is what my TA said re fuel surcharge:
"ALL bookings. This was the result of a lawsuit filed in Florida a while back. The cruise lines ended up refunding $$$$$ when the price of oil went down, but they kept the right to apply surcharges to established bookings if the price of oil went back up.
The max they can charge is $10 pp per day... but that is what they were charging when the rate was $140 bbl. If they add a surcharge, it may be much less than that."
Looks like we are all on the hook.
