5 stops
1.Grandstand
2.Carousel
3. Paddock
4.Congress Park
5. The Springs
The theme park buses all follow this order-I think (but am not positive) that the Disney Springs Bus stops at the springs stop first and then follows that same order. I haven’t stayed there in a few years and I know at one point they had a internal shuttle separate from the Disney springs bus. This still exists to service the tree house villas bringing them to and from the treehouses to the springs stop but I’m not sure if it also services the other 4 stops.
As for getting to other resorts your best bet for free transportation to any any non park resorts would be to walk, take the bus, or boat to Disney springs then transfer to the bus there to your desired resort. If you are headed to a crescent lake resort or MK resort you could take the bus to DHS or MK and then walk/take transportation (boat/monorail) to those resorts.
If you don’t mind spending $ Minnie Vans, Lyft, or Uber would be the quickest option.
