Homeless people in Hull who were set to stay in hotel rooms over Christmas had had their booking canceled.
Carl Simpson, founder of the Raise Roof Homeless Project, told the BBC that he paid £ 1,092 for 14 double rooms at the Royal Hotel in Hull, part of the Britannia Hotels group.
In a Facebook record shared by hundreds, Mr Simpson said he was "gutted".
An employee at the Royal Hotel told BBC on Sunday that no-one could comment.
Cafe owner Mr Simpson's post has been shared by hundreds, with most "scary" and "upset" at the decision.
Does MP Emma Hardy work on the post: "I would like to contact the hotel about this and appeal to them to rethink."
In the mail, Mr. Simpson says that the hotel was told what the rooms would be used for before booking and sharing the booking confirmation.
The reason for the cancellation is unclear.
Mr Simpson said that he had hoped to repeat "the success of last Christmas" when he could book 28 people for an Ibis hotel for two nights.
"After the stay, they were so grateful. Some left staff gifts with the little money they had, and one asked if he could vacuum the rooms to show his appreciation.
"This means the world for homeless people. Last year we had joy tears from someone standing on the edge of Humber Bridge the night before.
"We have to break the news to people whose hotel has been interrupted."
Mr. Simpson said he would not yet get a refund for the reservation, and could not rebook another hotel and added: "We need a miracle."
He said he rely on donations to make the original booking and he was worried about how many rooms needed could be found elsewhere at an affordable price.

Mr Simpson said he had a "big companion" in his local community: "Three years ago, my wife got five days to live.
"We received an emergency hospital at the hospital. I asked the public for help with a wedding dress and the support I received was fantastic."
He said he then took a hamburger to the city center to feed homeless "to give a little back".
"My wife came home after eight months and is still with me but she's very sick."
The Facebook post has inspired others to try and help the homeless in Christmas.
