Dunes called the Sauna Resort Hotel and made a reservation for his family of four for July 6-12. A letter of confirmation signed by the hotel manager stated, “This is to confirm your reservation for the period July 6 to July 12 inclusive. The rate for the Fern wood Cottage No. 10 Accommodation (American Plan) you requested is $600. A $100 deposit is required in advance to guarantee this accommodation. Please sign the original of this confirmation letter and return it to this office with the required deposit. Keep the other copy tor your files.” Dunes immediately signed and returned the letter along with a certified check for $100. In settling Dunes’s account at checkout time, the manager discovered that a typing error had been made in the quoted price of the accommodation listed in the confirmation letter. The quoted price should have been $700, not $600. Dunes refused to pay the additional $100 when requested to do so by the hotel manager. Can the Sauna Resort Hotel require Dunes to pay this additional amount based on the hotel’s error?
