I've been traveling all summer, staying in Courtyards and Marriotts, and have yet to encounter an unruly pack of children "destroying breakfast."

And not that I should really bother correcting any of the ridiculousness in the OP, neither Starwood nor Hilton is launching a new brand that is any more "business-centric" than Marriott's FS brands.

If anything, Starwood seems to be emphasizing its midrange offerings and Hilton seems to be emphasizing its upscale leisure offerings.
