Thomas Cook customers arriving at Manchester Airport in the early hours complained of vomiting, stomach cramps and diarrhea during their stay at Steigenberger.
Thomas Cook also said he had received reports of "an increased degree of illness among guests," a proposal rejected by the hotel management.
