It'd be great if one could log on the app before leaving the room or park and say where you'd like to go so there's some data *before* the bus stop itself. It's the difference between "reactionary" and "preventative" and would go a long way to decrease wait times and increase guest satisfaction scores to have the data to dispatch the extra bus before everyone queues at the stop.
This kind of existed for a time - ETA on buses getting to your resort. On my last trip I couldn't find it though. Not sure if I was looking in the wrong place (it was hard to find before) or if they removed it.
