LOS ANGELES | A special analysis of hotel spa department operating statements conducted by PKF Hospitality Research (PKF-HR) finds that a 9.7 percent increase in hotel spa revenues resulted in an 11.3 percent gain in spa department profits in 2006. Driving the increase in revenues was a 9.6 percent increase in the sale of such popular spa services as massages, body scrubs/wraps, and facials. Also contributing were gains in revenue generated from local membership fees, fitness lessons and personal training, and the sale of merchandise and clothing. These observations come from the recently released inaugural edition of Trends in the Hotel Spa Industry published by PKF Hospitality Research, an affiliate of PKF Consulting (PKF-C). The report is believed to be the most comprehensive analysis of hotel spa department financial performance in the industry.
