If you mean the resort bus stops at each park, no, not really. Why? Because they are not etched in stone. They can, and do change. So, if you are told that the bus stop for Pop is one of the first stops at DHS, that would be correct, but it may not be correct 3 months down the road.
And, there is no system involved. A resort that is at the park end of the bus stop at one park, can very well be at the very end at another park.
