Some 80 people were evacuated safely from the building last week when the fire broke out in the hotel kitchens, quickly spreading to the first floor and roof.
The hotel, which has been used as a set for Inspector Morse and Lewis, has remained closed since the fire. Hotel manager Michael Grange told the Oxford Mail the fire had caused "millions of pounds of damage". The worst affected areas are the ground floor and surrounding rooms and corridors.
"A lot of the hotel looks like it has not been damaged at all," said Grange. "Then you go to the back-of-house areas and you can see the damage is pretty devastating."
The hotel "will be open for accommodation from Monday 27 April", and will "hopefully reopen for meetings/events from Sat 02 May". The property is a favourite for conferences and events, offering six meeting spaces, with the ballroom able to host up to 400 guests.
The blaze has since been blamed on "perhaps too much cognac in a saucepan" while chefs flambéed beef stroganoff.
C&IT contacted Macdonald Hotels for an update, but was told it had not released an statement yet.
