You're not the first to report allergic reactions to Four Point's amenities lineup. The most surprising component of all of this is Casswell-Massey's willingness to license out its substantially good name to a mid-price hotel chain's amenities that are made in China.
To the OP: when you reported it to *wood corporate, did they make a note of your name and contact info? Did they advise that they'd be in touch with you further? Or, were you simply routed to Marietta directly? If so, have you been in touch with them?
