I dont know what to believe anymore. Both times I spoke with Tech Support today, they stated that my current home phone number is the number that is associated with my reservation. They also said it is the only phone number they have for me in the system, yet for whatever reason I still cant retrieve my resort reservation on the dining system. (It's not a DVC or TA ressie.)
Anyway, after poking around for awhile, the Tech Support CM suggested I try clearing my cookies and transferred me to Guest Services. The CM there advised me to get a hold of Tech Support! I got the distinct impression that they have no idea what the problem is.
