Two hotels being used to house child migrants have been fully booked by the Home Office until the end of the year.
The three-star venues on the south coast have been commandeered to secure extra accommodation for the record numbers of asylum-seekers crossing the Channel in dinghies.
It could mean a six-figure bill for taxpayers as some rooms can cost more than £200 a night.
The block-booking came as MPs told of 'shocking conditions' in a cramped office space in Dover where new arrivals are being held for days on end until they can be found homes elsewhere.

More than 9,000 migrants have made the treacherous journey across the Channel this year.
As many as 56 would-be refugees were moved into the Langfords Hotel in Hove, East Sussex, last week.
Phelim Mac Cafferty, leader of Brighton & Hove City Council, said they were 'deeply concerned' the Home Office had given them less than 24 hours' notice about the hotel's block-booking.
The Oyo Stade Court Hotel in Kent has also been fully booked by the Home Office until the end of the year.
The Government insists that unaccompanied asylum-seeking children and family groups are a priority at the Kent Intake Unit in Dover and are cared for by social services as soon as possible.
