Study Reveals One in Three Group Room Nights Are Booked Outside Room Block

August 7, 2015

A study jointly released by ASAE: The Center for Association Leadership, Center for Exhibition Industry Research, Destination & Travel Foundation, Meeting Professionals International and Professional Convention Management Association Education Foundation, revealed that on average, one in three group room nights in the United States are booked outside of the event contracted room blocks.

“Despite general agreement that many attendees book outside the room block, the meetings industry traditionally relies on the historical room block pick-up as one of the most important metrics to value an event,” said Christine “Shimo” Shimasaki, managing director of and Event Impact Calculator at Destination Marketing Association International.

She added, “This study proves that the method captures only a partial story and is the first of its kind to quantify just how many more overnight visitors the meetings industry is continuing to drive to destinations across the United States.”

Performed by Tourism Economics, an Oxford Economics Company, the study conducted ZIP code analyses for more than 170 events with over 880,000 attendee origin data provided by registration and housing companies, association management companies, destination marketing organizations, and individual meeting and exhibition organizers.

Events ranged from 60 to more than 55,000 attendees, across various market segments, event locations, and destinations from 2012 to 2015. The research took a conservative approach to event room demand, estimating that only those attendees with ZIP codes more than 100 miles from the meeting locale required a guest room.

While on average 34.1 percent of rooms are being booked outside the contracted room block, study findings showed significant variation in the proportion of rooms booked outside the block, which can be explained in part by certain event characteristics.

“Across the sample of events studied, the variation of the share of rooms outside the block was quite large, so it's critical to avoid applying the every third room assumption across all events” said Christopher Pike, Director of Impact Studies at Tourism Economics.

He added,  “Factors including event size, facility gross square footage, market segment, and length of an event all influence the share of rooms booked outside the block, and we have a tremendous opportunity to match room demand with an event more closely.”

The industry-wide collaborative study introduces a new metric of event room demand that will provide planners, hoteliers, and DMOs an additional lens through which to consider room block pick-up performance.

Taking event room demand into account produces significant benefits to all parties. An event avoids running the risk of being undervalued due to a high proportion of attendees and exhibitors booking rooms outside of the block.

As a result, the meeting planner also minimizes difficulties in securing adequate exhibit and meeting space for future years or underestimating its room block requirements in destinations that have limited hotel supply.

Likewise, DMOs avoid underreporting overnight attendance and by extension, economic impact of an event, and hotels are well prepared to meet actual room demand. In addition, stakeholders such as media and local politicians unfamiliar with industry trends, will be less likely to underestimate the value of events.

Association Leaders Weigh In:

“The data from this collaborative research project provides credible information supporting what many organizations suspected was true about their total room pick up, inclusive of rooms booked inside and outside the room block.  And that number represents the overall value to the city.  Organizations working with their DMO partners can now more accurately value, plan, and implement successful events.”

“For the first time we have empirical data that shows that on average a third of all hotel rooms are booked outside the contracted room block. There needs to be a shift in thinking by hotels and CVBs that the overall economic impact to a city of an exhibition or event is higher than what is currently being calculated. For exhibition and event organizers, this is critically important when they are negotiating hotel and convention center space.”

Sporting events are no longer the most preferred target for terrorists, according to the Department of Homeland Security. Outdoor events, conferences, festivals, and other events featuring public figures are all vulnerable. And with over a thousand different-level attacks since 2015, it’s no surprise that safety and security are among the top concerns for event professionals.
