Sonnenhotels GmbH

What Sonnenhotels GmbH does

Sonnenhotels GmbH is a private German hotel management company headquartered in Bad Harzburg, Lower Saxony, operating as the central service center (Servicezentrale) for a portfolio of regional leisure hotels and resorts across Germany and Austria. The group operates through five wholly-owned subsidiaries covering properties in the Harz, Erzgebirge, Bayerischer Wald, Fränkische Weinberge, Salzburger Land, and Tirol regions, with each property individually branded and positioned (e.g., the Weingut Römmert wine hotel, the all-inclusive Bayerischer Hof family resort, the Hoher Hahn activity hotel, and the Sonnenresort Ettershaus). A partner-network model adds Post Seefeld Hotel & Spa in Tirol to the distribution surface without consolidated ownership.

Revenue is generated primarily through direct accommodation bookings (rooms with breakfast always included, plus half-board and all-inclusive tiers at select properties), supplemented by ancillary F&B, wellness, spa, golf, and activity revenue streams, gift voucher sales, group/bus-travel packages for 20-100 persons, and a referral commission from a Hanse Merkur travel-insurance partnership. Distribution runs through a 24/7 direct website (sonnenhotels.de) and centralized phone booking service, complemented by travel agencies, tour operators, and an expanding paid digital marketing footprint (Google Ads, Bing Ads, Meta, Brevo email/SMS).

The technology backbone is built exclusively on third-party SaaS — Vioma for the Internet Booking Engine, Apaleo for the Property Management System, CODE2ORDER (Straiv) for digital check-in and guest messaging, ReGuest for offer management, and MAIC for the digital concierge — layered with Microsoft 365, PCI-DSS-compliant payment routing (Hobex, PayPal, Sofort/Klarna), and GDPR-compliant operations managed with DataCo GmbH as data protection officer. The group is led by Managing Director Christopher Schach (Geschäftsführer); no founding year, financial figures, or headcount beyond a 101-250 firmographic band are publicly disclosed.
