Revenue per available room has climbed 15 percent year-over-year, based on reservations on the books for the upcoming 12 months, according to data just released in the April 2012 TravelClick North American Hospitality Review. That includes group sales commitments as well as individual reservations that have been booked for April 2012 through March 2013. Group business is driving occupancy growth, with a 5.9 percent increase over a year ago, while group average daily rate has shot up by 6.4 percent. Transient business, meanwhile, is up 7 percent, with rate increases of 8.2 percent for weekdays and 8.1 percent for weekends. Committed overall occupancy for the second quarter is currently up 4.6 percent over last year, and average daily rate on the books for the upcoming quarter has increased by 6.9 percent. "Our TravelClick data has consistently shown increases in demand across all travel segments during this early part of 2012," said Tim Hart, executive vice president, enterprise services, in a statement. "Hotels are continuing to drive their bookings and target different types of customers to maximize their profits."
