I did! I kept trying, and even tried to make a new account, but they kept giving me a message of "this email already has an account associated with it".
I also kept asking them to send a new password, thinking that was the problem. They would send it to my account, and I would copy and paste the new password under my email address, and it would tell me "incorrect password". Finally, I tried one last time with my original password, and it logged me in! I ordered my parkhopper tickets and WOC package, and then later when I tried to log in again, it wouldn't let me.
So something is going on!
