A passenger on the luxury cruise ship stuck in Greenland said her biggest fear before being freed was running out of alcohol

• A passenger on the stuck Greenland luxury cruise ship said her biggest fear was running out of alcohol on board.
• Luckily, the ship, which ran aground on Monday, was finally freed Thursday morning.

A passenger on board the stuck luxury cruise ship in Greenland told CNN that her biggest fear while stranded for days was that they would run out of alcohol on board.

"That is the biggest concern I have," the passenger, named only as Lis, told CNN affiliate Nine News.

She added that she took swimming lessons before boarding the cruise and could swim back to Iceland if need be.

Luckily, the ship was freed Thursday morning, according to CNN.

The Ocean Explorer, a luxury cruise ship carrying 206 passengers and crew, ran aground earlier this week in Alpefjord.

Denmark's military Joint Arctic Command said the ship was finally pulled free by a fishing research vessel on Thursday.

Many feared the cruise ship could have been stuck for days after several failed attempts to refloat while waiting for a large Danish naval ship to come help, according to CNN.
