Same here!
I have totally given up - I have contacted Disney because I thought it was the fact that I work on a Mac..., but they tell me their site is working fine and that being on a Mac is not an issue. They suggested I clear the cache, clear all cookies, etc. which I have done and still nothing. Since they started rolling out the new games, etc. their site has never been right. It will be a bummer if I can no longer get on their reservation system to check out pricing - I like to do that first, before I contact either WDW directly, or an agent.
I hope someone from Disney is watching these boards. I do not think we are alone, either. I am reading about more and more people having problems with the site. All I can say is at least I am not the only one. I really thought I was starting to lose my mind when I could not get on.
