The routes and resort groupings are very fluid. BUT, having said that, the times I have taken DME to POP, the bus has also gone to AKL Jambo House and Kidani, as well as CSR. Pop was usually the first stop, but on one occasion, the bus headed to AKL first.
But, remember, that isn't etched in stone. Figure on it taking you an average of 70 mins to get from gate to resort.
