          <h2>Efficiency is the luxury.</h2>
          <p>
            Opened in 2008, Meridian was designed for the professional who needs everything to work —
            reliably, quickly, and without friction. No over-the-top lobby chandeliers. Clean lines,
            fast internet, and a team that anticipates your needs before you ask.

          <p>
            We partner with DAX 40 companies and international event organisers who need a hotel
            that keeps pace with them. Over <strong>15,000 corporate stays</strong> later, our
            repeat rate speaks for itself: <strong>74% of guests return</strong> within the year.

Business Hotel Landing

A clean, corporate single-page landing for Meridian Business Hotel — an efficient city-centre property built for professionals. The page presents a structured navy-and-steel hero with an inline booking widget, three guest room cards, a conference and meeting rooms section with capacity specs, a business amenities grid, a story/about block, and a location + hours strip with a CSS map. The booking widget calculates stay totals live, validates dates, and fires a toast on submit. A sticky nav transitions from transparent to solid on scroll. Layout collapses responsively at 960 px and 560 px.
