Radisson's US E-mail Address?

Radisson's US website does not appear to list an e-mail address.

Can anyone advise what it is?

I have been liaising with an individual within Radisson and whilst I do not think it appropriate to give his email, they end in @radisson.com I am sorry I can't help further, but if you know whom or what department you can prefix the above and should get a reply, ie customerservices@radisson.com. I don't know if this address works but good luck.
