Officially, a 7-star rating is impossible. Across the world, fairly uniform hotel classification systems are used, particularly in instances of international standardisation, such as the European Hotelstars Union (HSU). According to these systems, the maximum rating a hotel can achieve is officially 5-stars.

Officially, the international hotel star rating system only goes up to 5 stars. Organizations like Forbes Travel Guide and AAA utilize a 5-star or 5-diamond scale as their maximum. However, the terms "6-star" or "7-star" are frequently used in marketing and by the media to describe properties that offer a level of luxury, service, and amenities that far exceed the standard 5-star criteria. The most famous example is the Burj Al Arab in Dubai, which was first described by a journalist as a "7-star hotel" during its opening, a label the property has since leaned into for branding. Other hotels that are often unofficially called 6-star or 7-star include the Emirates Palace in Abu Dhabi, the Laucala Island Resort in Fiji, and the Pangu 7 Star Hotel in Beijing. These properties typically feature personalized 24-hour butler service, private helipads, gold-leaf interiors, and guest-to-staff ratios as high as 6:1. While no formal regulatory body grants these "extra" stars, they serve as a widely understood shorthand for the "ultra-luxury" segment of the hospitality market, where the price per night often starts in the thousands of dollars.
