I do not know for sure.
CSR is the one resort that is tricky
It has individual gates that operate using a MB inside the complex, vs 1 main guarded gate. The guarded gate is closer towards the tower. It's my understanding that you can't get picked up anywhere they have to go through one of those gates. We have only stayed at the tower so no first hand knowledge. They can reach the tower, they tell the guard they are there to do a pick up.
At any rate, they should never pick you up at the bus stops, those are for buses only. They would go to wherever a private car can go. So closer to a building parking lot
