The local news is reporting that the Courtyard Waikiki Beach has been sold by it's current owners to Highgate Hotels. There's no information on future property management/branding at the moment, however, Pacific Business News does report that the new owner has the option of operating the hotel under the CY name through 2034. I believe the property is currently owned by Outrigger Hotels & Resorts, while the article states that the new owner, Highgate Hotels, is the current property manager.
In similar news, the Hyatt Regency Waikiki has also been sold to Blackstone Group (Hilton). Blackstone promises $75 million in renovations (hint hint Marriott), while Hyatt will remain the property manager.
