Both companies are owned by the Malvern Group which went into administration on Thursday, leaving an estimated 53,000 customers in doubt over holidays they had booked.
A statement on the Malvern website read,
"We regret to advise you that Malvern Group incorporating Superbreak Mini Holidays Limited and LateRooms Limited, has filed a Notice of Intention to Appoint an Administrator on 1st August 2019 and have ceased trading with immediate effect.
"It is the company’s intention to appoint an administrator to deal with the affairs of the business tomorrow."
The advise for those with concerns over bookings with LateRooms was to contact the hotel directly.
LateRooms went on to say,
"In relation to your forthcoming booking(s), LateRooms.com acted as an agent on behalf of your accommodation supplier therefore we anticipate that your reservation is secure and your payment will be taken by the accommodation supplier either in advance (for non-refundable reservations) or at the property.
"LateRooms limited have not taken any payment for your booking.
"We recommend however that you contact your accommodation supplier directly prior to travelling to confirm. You can find their contact details on your booking confirmation.
"To amend or cancel your booking you will need to contact the accommodation supplier directly."
It advised SuperBreak customers to contact Abta, their travel agent or their credit card provider for further help.
Abta has issued advice for customers of SuperBreak, but said it did not cover LateRooms.
In a statement, it said,
The "vast majority" of SuperBreak holidaymakers' arrangements would be covered through Abta, Atol or their credit card companies.
"These customers will either be entitled to a refund or, if they've booked through another travel company, they should contact them to discuss options which may include continuing with their booking, re-booking or alternative arrangements,"
