In a statement to its members on Wednesday, the American Society of Travel Agents (ASTA) announced that it had expressed concerns to Marriott International HQ about the new policy.

"Our message was clear: the policy discriminates against consumers who use travel agencies and is not likely to be well received by them," said ASTA president and CEO Zane Kerby in the statement.

"We explained our understanding that most travelers now expect Wi-Fi to be available when traveling. Marriot’s plan to offer free Wi-Fi as an inducement to travelers who book direct with a Marriot brand or through Marriott.com will disadvantage loyal travelers who use the travel agency distribution channel."

Under the new policy, Marriott Rewards members who book directly through Marriott.com, Marriott's mobile app, 1-800-MARRIOTT or through a Marriott hotel would receive free standard Wi-Fi, starting January 15, 2015.

ASTA said that it is not issuing any public statement at this time since it is still currently in discussions with Marriott.
