Design Hotels AG entered into a Services Agreement with Starwood Hotels & Resorts Worldwide Inc. and its subsidiary company Preferred Guest Inc. on November 9, 2015, which allows Design Hotels AG to connect a selection of its member hotels to the Starwood Preferred Guest customer loyalty program and Starwood's distribution channels. This enables Design Hotels to further expand the product and service offering to a selection of its member hotels. The participating member hotels will get access to a very successful customer loyalty program in the international hotel industry.

Additionally, the participating member hotels will benefit from the connectivity to Starwood's distribution channels: Starwood websites, the SPG mobile application, and the customer contact centers. All connectivity within the Design Hotels reservations system will remain unchanged.
