You can hook into the side of the phone for a modem connection. NONE of the WDW resorts have public high speed connections.
My guess is that if they ever decide to add them to any resorts, they will first start with the ones that attract business people, The BWI, YC, GF, CR, CSR. They will also charge a premium to sue this connection. I highly doubt they will bother with the ASR in the forseeable future, the return is simply not worth the investment.
