How this is compiled
Each entry begins with the hotel's own pages and is checked against mapping services, architectural writing and press coverage. Where two sources disagree, the entry says less rather than more. Nothing is written from memory, from marketing copy alone, or from a stay that cannot be shown in a published record.
The three groups in the index above describe the building, not the section: houses adapted from an earlier use, houses raised as hotels, and structures built again from snow each winter. The full method, and how to report an error, is set out on how this is compiled.
