He also told The Sun that he had "no idea" what the man was doing.
Members of the Facebook Group have found much humour in the old man's appearance and have tried to explain the situation.
"Maybe he got himself locked out of his room," one group member said.
"At first I thought this was photoshopped," another confessed.
Other group members weren't fussed by the old man's no show of clothing saying: "Come on it's no different than Euros wearing banana hammocks at the pool."
Another, who used to work in a hotel lobby, revealed that this "happens all the time".
Other group members have shared images of filthy hotel rooms as well as guests passed out in hotel corridors.
An air hostess even left her very large sex toy in a hotel room and a public note was made to inform flight crew it had been found.
