There is only one entrance/exit for the resort- it enters from Community Drive and is noted at the top of the map as Conch Flats. The usual route within nthe resort is to stop first at Peninsular Road, South Point, Old Turtle Pond, Miller Road and Hospitality House. The bus returning from DD will stop at Hospitality House first, run the other stops and then stop again at HH before leaving the resort for DD.
Usually, every bus will stop at HH before leaving the resort, so that is an easy means to get to the pool/Olivia's/Conch FLats Store/Front Desk. If there is any doubt about the route for a particular bus, just ask the driver. They're always happy to help.
Enjoy!
