The numbers will be different at each park. Note all the directions are as you leave the park
POPs STOPs
MK - Stop #18, stay all the way to the right and its the last stop (very far)
AK - Stop #12, stay all the way to the left and its the second stop
HS - Stop #9, stay all the way to the right and its the third stop
EP - Stop #12, go past the information booth make a right and it is the last stop
DTD MP - Stop #8, first stop on the right
DTD PI - Stop #8, last stop down
I guess you have to take the good with the bad when staying at POP. POP has some of the longest walks to get to your bus stops at the parks but on the other hand POP resort has only one stop and it doesn't share with other resorts making the duration of the bus trips to and from the parks very short
