The three biggest conventions so far - the Association of periOperative Registered Nurses, Lightfair International, and ISTE - filled up all 44 Center City hotels, Ferguson said.
That underscored the need for 1,500 to 1,800 more rooms, he said, because several suburban hotels, such as the Holiday Inn in Cherry Hill, also benefited.
The American Transplant Congress, which is based in Mount Laurel, drew 5,000 participants and booked 15,547 hotel rooms over five days.
Although the group - physicians, surgeons, and transplant organizers - gathered mostly in the original portion of the Convention Center, Pam Ballinger, vice president of meetings and exhibits for association headquarters, said she liked how the buildings seamlessly connected and shared color schemes.
