A hotel classification audit is an assessment of a hotel's facilities and services to ensure that they meet the criteria set by a particular classification system. Hotel classification systems vary by country and region and may be based on factors such as the hotel's amenities, room sizes, location, and overall quality.

The audit typically involves a detailed inspection of the hotel's facilities and services, including its rooms, dining options, leisure facilities, and customer service. The auditor evaluates the hotel based on predetermined criteria and assigns a classification or rating based on the hotel's performance against these criteria.

Hotel service quality certification is a third-party certification that recognizes a hotel's commitment to delivering high-quality service to its guests. The certification is typically awarded to hotels that meet certain standards of service quality, based on an independent assessment of the hotel's facilities and services.

There are several hotel service quality certification programs, such as the Forbes Travel Guide, AAA Diamond Ratings, and the Hospitality Assured Certification. Each program has its own set of criteria for assessing service quality, which may include factors such as cleanliness, comfort, amenities, dining options, and customer service.

A guest experience study, research, and benchmarking for a hotel involves evaluating and analyzing the quality of service and overall experience that guests have when they stay at the hotel. This process can help the hotel identify areas where improvements can be made to enhance guest satisfaction, improve repeat business, and increase revenue.

The study typically involves collecting feedback from guests through surveys, feedback forms, and online reviews. The hotel may also conduct interviews or focus groups with guests to gain deeper insights into their experiences. The data collected is then analyzed to identify patterns, trends, and areas for improvement.
