A great deal of primary and secondary research has been conducted by Hartland Hotel Group principals on hotel customer preferences. This research has informed the designs of over70 hotels where its validity was tested and refined. Fashions change over time and interior design concepts need to be responsive, but the basic functionality of the hotel never goes out of style. It makes the hotels easier to operate, they become more profitable and at the time of sale, the new owner does not feel compelled to fix it. All of which leads to a higher sales price. Once the functionality is established, the hotel’s decor and its restaurant and bar concepts and other amenities need to be relevant to the target customer. This also requires research with the recognition that the shelf-life of this aspect might only be 5-7 years.
