Who do you contact to recognize good service? DP and I stayed at the Marriott Copley Place in Boston and had a delightful encounter with one of the concierge lounge attendants. Prior to check out, I asked the front desk who the manager was and was told it was David Giblin. I confirmed this on recent press releases and sent an email to david.giblin at marriott.com, but the email bounced. Any suggestions as to how to compliment this employee? The website drives you to the MR portal. That doesn't seem like the right place to leave my feedback.
