Why do Expedia and Travelocity offer cheaper rooms?
On-line travel services have extensive buying power at most hotels which gives lower rates on a very limited number of rooms. These rates are not available for convention groups because they extend to usually fewer than 10-15 rooms per night. However, if 15 members book through Expedia and 15 more with Travelocity for 5 nights, GWA loses 150 room nights in its meeting block which could potentially cost everyone thousands of dollars in higher registration costs.
