Afraid not, this was the answer given when I asked them the same question
"Dear Mr Lambie
Thank you for your email, which I forwarded to my Manager for his input.
I have been advised that we are not at this time removing/reducing fuel levies, as this possibility was looked at for the season some time ago.
The industry will be monitored but cruise operators such as Royal Caribbean and P&O and Carnival Cruise lines will be driven by the U.S market /guidelines for their decision on refunds.
I hope this has answered your question for you "
