It is mandatory for guests to present valid photo identification at the time of check-in. According to government regulations, a valid Photo ID has to be carried by every person above the age of 18 staying at the hotel. The identification proofs accepted are Driving License, Voter ID Card, and Passport. Without valid ID the guest will not be allowed to check-in.
PAN cards are not accepted as a valid ID card.
