A friend of mine sent me a copy of a newsletter they had received from the Embassy Suites Fallsview. The newsletter says that she received it because she had stayed at a Hilton (corporate head of Embassy Suites) hotel before. Also, the email from sent from the Hilton corporate mailing list as opposed to something local.
Essentially all the newsletter does is take you to the main Embassy Suites site with the Embassy Suites Niagara Falls / Fallsview page showing.
