In 2009, Ms Booth appeared in BBC Wales fly-on-the-wall documentary series Hotel Stephanie showing her cope with the day-to-day problems of managing six hotels in north east Wales during the recession.
In recent months she has been linked with a takeover of Wrexham football club, before withdrawing from the process in May.
She took over the Wynnstay Arms, which is a well-known Wrexham landmark, in April 2010. The new proprietor "guaranteed" the workforce their jobs would be safe.
A spokesman for Ms Booth said on Thursday that she had been using her own money to ensure all staff were paid prior to the administrators being appointed.
