Hotel-keeper's contracts are divided into three basic types: direct, agency and allotment. Direct hotel-keeper's contract is concluded between hotel-keeper and guest, while the parties of agency and allotment contract are hotel-keeper and travel agency. Hotel services are provided by same contracts, for a fee, with the eventual payment of commissions. The dissertation analyzes contracting parties' (hotel-keeper, guest, travel agency) liability for damage due to breaching of hotel-keeper's contract in Croatian and comparative (French, German, Italian, UK, USA, European and international) law. The thesis is composed of ten chapters and consists of a general and a special part. In the general part of the paper, in the second and third chapter, notion, types and sources of law on the hotel-keeper's contracts are processed, as well as the debtor's general liability for proprietary and non-proprietary damage due to contract breaching. A special part of the paper, from the fourth to the ninth chapter of the paper, deals with contracting parties' (hotel-keeper, guest and travel agency) liability for proprietary and non-proprietary damage due to breaches of the direct, agency and allotment hotel-keeper's contract in the Croatian and comparative law. Due to breach of the hotel-keeper's contract, the proprietary damage (ordinary damage and lost profit) and non-proprietary damage (injury of reputation, ruined vacation, stay objectives failure, anxiety, discomfort, dissatisfaction, physical and mental pain, etc.) can be compensated. In the Croatian and comparative law, the direct and agency hotel-keeper's contract must find its legislative position, and on the comparative law level the unification of the hotel-keeper's contracts is required; therefore the draft UNIDROIT Convention, ECTAA-HOTREC Code and IH&RA-UFTA Code should have been the foundation of the international Convention on the hotel-keeper's contracts.
