Olivia Elliott told Sky News: "We were all sat upstairs when the alarm went off and the captain came on the tannoy and told us to evacuate to the outer deck because there was a fire.
"We were out there for about 40 minutes and then we had to wait in the nightclub area.
"We are now back in our rooms. We don't know when we will be allowed to leave the ship."
