The Adventure Travel Trade Association is seeing remarkable success in its third year since it relaunched. ATTA membership is on the rise, more than doubling in the trailing 12-month period to over 480. Additionally, in its third annual Adventure Travel World Summit being held October 4-7, 2007, in Whistler, British Columbia, the ATTA has: sold out its executive event at its 500-delegate capacity; sold all of its sponsorship opportunities; and sold out all exhibition space. The 500 delegates come from over 30 countries worldwide and represent over a 60% increase in attendance from the first Summit held in 2005.
