Proprietary scale to 9
Drill System
Our proprietary drill scale goes to 9—surpassing classic five-star framing. Tiers 1–5 define the classic ladder; 7 is ultra-luxury beyond five-star; 9 is ultimate and category-defining.
2 Drills · Preferred Quality
Stronger facility completeness and service consistency—stable breakfast, front-desk response and room comfort.
3 Drills · Distinguished Stay
Aligned with mainstream premium hotels: refined spaces, F&B and business amenities, professional service and clear brand identity.
4 Drills · Refined Luxury
Distinctive aesthetics, deeper concierge care and memorable moments—ideal for premium business and leisure.
5 Drills · Classic Icon
The classic five-star-analogous peak: extreme detail, bespoke service and unified brand narrative—the reference bar before ultra-luxury tiers.
7
7 Drills · Ultra-Luxury
Beyond five-star: private rituals, narrative environments and elevated operational precision for guests and owners seeking true ultra-luxury.
9
9 Drills · Ultimate
The ultimate, category-defining height of the drill scale—rarity, originality and irreplaceable brand equity as the industry reference.
Criteria span hardware, soft product, service, safety and brand presentation. Tiers 7 and 9 are proprietary advances beyond classic five-star framing. Detailed rules and licensing terms are defined in formal agreements and current standard documents.
