A British tourist described the scene at a hotel in Tunisia, which refuses to let guests leave the Thomas Cook affair as "a hostage situation".
Guests at the Les Orangers resort in Hammamet, Tunisia, say security guards keep the door closed while the hotel requires visitors to pay extra money for fear of being owed what Thomas Cook owes for a booking reservation.
Ryan Farmer, of Leicesterhire, said the hotel had invited all guests who needed to go to the front desk on Saturday afternoon "to pay extra fees, apparently because of the situation with Thomas Cook."
Given that many tourists defied demand because they already paid for a travel company with the mainland, security guards closed the gates of the hotel, refusing guests to let or let new visitors.
"We cannot leave the hotel. I would describe it as exactly the same as holding hostage," Mr Farmer told the BBC's Stephen Nolan Show.
"We were at the door. There were four security guards at the door who closed the gates and couldn't let anyone in."
He said the guards did not respond to requests from guests to be allowed out.
"They say nothing. They just stand there and hold the door," he said.
"There was a gentleman from Ireland who was trying to talk to security guards and he said, 'Look, we want to go home, we want to go home. Can you let us out? They just look at him and laugh and keep the door closed.
Mr Ryan said a woman in her 80s had been paid a hotel 'more than £ 2,000', though she had already paid Thomas Cook for her vacation.
"Representative Thomas Cook is trying to work things out with the hotel, but they're just not interested," Mr Ryan said.
The British Consulate in Tunisia was reportedly aware of the situation at the hotel.
Thomas Cook convened a meeting of major shareholders and creditors Sunday morning to avoid coming to the board.
