Notwithstanding section 1323 (relating to liability for property loss or damage), a hotelkeeper or campground owner may, by special arrangement with a guest, receive any property for deposit in the safe or vault upon terms as to which the parties agree in writing, but the hotelkeeper or campground owner shall be liable for property loss or damage after the articles have been accepted for deposit, if the loss or damage is caused by theft or negligence of the hotelkeeper or campground owner.
