A hotel may require any guest, or person proposing to become a guest, to enter into a special contract as to the duration, kind and place of board, entertainment, or lodging to be furnished such guest and the price therefor to be paid. If such guest refuses to enter into such contract and to accept board, entertainment, or lodging under the terms and conditions so proposed by the hotel, the hotel may refuse to receive or entertain such guest and because of such refusal shall not incur any liability whatever. Such special contract must be in writing and signed by both parties, and by such contract a hotel may vary its liability for the safety of the goods of its guests.
