Just look at this page and tell me if you notice anything strange about the list of Marriott Reps - it's like a super secret underground list of insiders that have sailed into the Bermuda Triangle and were (or at least some) seldom or never seen again.
Actually the date is quite relevant. Things on this site change and links are not always updated to reflect the current info. If you really want the "secret menu" how about clicking on the "The Insiders Guide" that appears at the top of the welcome page (shown above)?

I suspect this might be what you were looking for. At least it was posted within the past few months, so is likely more relevant. There was a fairly major site overhaul earlier this year. Granted many of the links were not updated to reflect the changes. In the grand scheme of things, that's the least of our worries.
