Every now and then, I look into the Disney Springs hotels but for us, the deciding factor is always transportation. We like the convenience of the Disney buses and the fact that 90% of the time, they arrive every 15-20 minutes. We don’t want to deal with rental cars, parking, traffic etc on our vacation. If the Disney Springs hotels ever up their bus service, we would certainly make the switch now.
For the cost savings you could take Uber just about everywhere, likely saving time and money. Only exception is MK but a Minnie Van will take you right to the gate.
