What is this MICE acronym?
I see, Meetings, Incentives, Conferences, Exhibitions
My feeling is that the top luxury hotel groups want to distance themselves as far as possible from that kind of image, which makes sense as it is not their target market. FS/MO/Pen etc.. cater to high end leisure and business travelers, and also host small to mid sized business or social functions, as well as high end weddings in certain markets.
Grand Hyatt does a very nice job of managing larger, upscale properties that can accommodate much larger events and functions. They typically have large ballrooms, various other event spaces, and F&B departments that can handle catering for such large numbers of people.
Grand Hyatt Tokyo is an example of a property that successfully wears two hats. It caters to large functions and groups of business travelers, but is also capable of providing a high level of personalized service and can meet the needs discerning travelers (at club room and suite level).
