We have used the e-mail section on disneyworld.com to both complain and compliment. You always get an immediate generic response that they received your note. After a couple of weeks or so you will receive a specific e-mail regarding your complaint or compliment. A couple of times we have received telephone calls from the WDW Executive Offices to talk about our e-mails. Whether you are complimenting or complaining be as specific as possible. If possible use names, dates and locations. Disney takes the e-mails they receive very seriously. I know that a compliment we sent a few years ago was documented and placed in the Cast Members personnel records.
