Anyone that has tried to do anything online with Disney over the past day or so will tell you that IT and Disney is not a match made in heaven. For some reason, they just can't get it done!!
And those bus arrival boards? Because there is traffic out there, and traffic lights, there is no way to be 100% spot on when dealing with arrival times. I have sat and watched as bus after bus arrived, to parks I had no interest in going to. While I sat and waited for my bus to MK! The time changed by almost 30 mins from the time I arrived. First it said one thing, then 10 mins was added. Then shortened by 5 mins. Then increased by 10, then another 10!!! I sat there for about 35-40 mins!!! Was about 15 mins late for my ADR! I know full well how to use the transportation, I had planned correctly, leaving about an hour to get to MK from OKW at 10:30, for an ADR at 11:45. When Disney says to plan on 90 mins? Yeah, they need to cover their collective behinds, just in case it does take you more than an hour.
So, no....having arrival times on your TV is a recipe for disaster!!!
