You could call the passholder hotline and give them your e-mail address. I think it's 407-560-PASS. They don't email all the rates, just the announcement that the rates are being released.
I asked this last week and was told to sign into the Disney site under the passholder section and there is an option there to receive emails about things like this. I haven't tried it yet, but will soon!
I got an email for the AP rates thru April, but this round no email. I'm not sure what happened. I am signed up on the site, and I checked to see if it had been sent to my spam blocker, but there was nothing.
For some reason, I never get emails from Disney to my AOL account. It's not in my spam folder and I am signed up for everything. Dh does get some emails from them in his AOL account. I don't know why I have such problems!
I got a free go.com email address and have changed all my Disney site info to that and have been getting most of the Disney stuff now. (You would think that since it's a Disney site I would get all, but I still don't get disneydirect.com stuff )
