The following is offered for Platinum and Gold members:
"Free High-Speed Internet Access: Complimentary Internet access at all JW Marriott, Autograph Collection, Renaissance Hotels, AC Hotels, Marriott Hotels & Resorts and Courtyard by Marriott (outside of U.S. & Canada only). Not available in meeting rooms."
Note that free WiFi is offered at Courtyard outside of the US and Canada only. This seems to be a curious change from previous years. That said, I have had free WiFi offered at recent Courtyard stays in the US.
