I am a huge fan of steam rooms and was wondering what Marriott's have them? I have stayed at only 2 properties with Steam Rooms but would love to see a list of places that have one.

JW Marriott Grand Rapids, MI
Has 2 steam rooms 1 Eucalyptus Scented, 1 not scented

Marriott Resort and Spa at TPC Sawgrass

The only other Hotel I have recently been in that has one is the Ritz Carlton Cleveland, OH (Just an FYI )

I heard the Renaissance in Downtown Chicago has one, but can not confirm through experience.
