The Neemrana Hotels, which manages the palace, has put room bookings on hold till Oct 25, an employee said Tuesday.
"We don't know what will be the role of the palace in the marriage but renovation is being done," a palace employee, who did not wish to be named, told IANS.
For the last one month, Saif's mother, Sharmila Tagore, has been visiting the mansion regularly, he said.
Saif's father Mansoor Ali Khan Pataudi, who died in New Delhi Sep 22 last year, and his forefathers are buried in the palace compound.
On Pataudi's first death anniversary, Tagore told reporters that her son's wedding would be held in Mumbai and the reception in Delhi. She did not mention Pataudi Palace as a possible venue.
"According to my knowledge, it is routine renovation. I do not know more than that," Neeraj Jain, manager of Pataudi Palace-Neemrana Hotels, told IANS.
