It depends on where you are staying. It seems that the Deluxes and most of the Moderates have WiFi. The Ethernet system (wired) costs $9.95 per 24 hrs and as said, all internet at Disney is slow plus they packet shape. So if you are trying to upload something (video, image so on) it will slow down into the double digit kilobyte range. I would bring your computer, it is useable for most applications. I bring mine every time we go.
