I could see it becoming a Sheraton under the Starwood brand. Sheraton are usually decent but can be run the range of modern to dated. At least the Starwood brand has strong business traveler appeal with their strong loyalty program.

Doubtful it would be a Marriott property considering Marriott has the Dearborn Inn plus an affiliation now with The Henry as part of their Autograph collection.

The Hyatt always did a pretty good business with meetings, seminars, and events. That at least should make the property somewhat desirable however it seems large in terms of the number of hotel rooms.
