I'm glad to see that he followed up with you on your comments, IME that usually doesn't happen, and especially to let you know of a positive change that came about from your comments. Several of us received e-mails yesterday from Alex as well. Nice touch on both counts.
FWIW, I did talk to one of the managers while we were there about doing a group deal at the Westin for next year. They're definitely willing to work with us if we want to work with them.
