I think "Slow" is the nicest thing I have heard said about the site since it launched. It is TERRIBLE!!!! I am struggling to do the simplest things like book a dining reservation. I have been trying for 3 days and just keep getting server busy message. Today I tried to add my email to received special promos and even that would not work.
I certainly hope that Disney realizes what a failure this is and is working around the clock to fix it!
