Passengers aboard Royal Caribbean’s Oasis of the Seas got considerably more ocean than they probably paid for this weekend.

Footage posted by the Royal Caribbean fan account Loyal to Royal shows the enormous cruise ship muscling through seriously rough Atlantic seas as it headed north from the Bahamas toward Cape Liberty, New Jersey.
