Yes, I've been trying to get on for the last hour with no luck. Probably just magically Disney I.T. at its finest. (unless they are specifically targeting us Cubs fans )
I had the same problem earlier today. Now I can get in, but I can't get the Resort Availability Tool to work. It will let me check for availability the old fashioned way, though . . . so at least that's something.
It's either fixed now or whatever the issue happens to be, it is only affecting some members. I just got off the site and had no problem accessing the RAT or other pages on the Member website.
It's OK for me now, including the RAT. Now ... if whoever has a BWV SV 1BR booked right in the middle of my stay would please cancel their reservation I'll be much happier!
