Disney is just an MVNO for Sprint who actually owns your phone number. They did the same for a few other companies like Boost, ESPN Mobile, Virgin. So if you were OK with the coverage like you are getting a good signal at home and the Palms poker room (your 2nd home from what I hear) then you can go to them, get a free phone and continue on. But there are always good deals to be had with other carriers especially if you want to switch. I've had bad luck with Sprint but that is just where I travel.

But its still a crappy thing to do.
