Just got back from staying at Hotel New York - I'm from the US and was planning to buy an international plan from my cell provider, but the wifi was so good I didn't need to. We relied exclusively on the wifi. There's wifi at each hotel, at Disney Village, and in the parks, so staying at Hotel New York we had wifi the whole time. You have to sign in - put in your name, email address, accept terms of service - but no password is required. It was plenty fast enough to check wait times, buy premier access passes, and even to join the Hero Training Center virtual queue.
