Just saw this posted on the luxury hotels board:

"On July 31, 2015, Four Seasons will be concluding its management of The Ritz-Carlton Chicago (A Four Seasons Hotel). Effective August 1, 2015, the Hotel will become a full participant in the Ritz-Carlton system. This means that the Hotel will no longer be a Ritz-Carlton in name only, but it will be a part of the Ritz-Carlton family of hotels."

Could be a new interesting option.
