We always stay in the Turtle Pond area. When I want to go to the HH, I jump on the very first bus that stops ----- always asking to be sure that the driver is planning to stop at the HH (one time a driver didn't, and people were screaming for him to stop, but that only happened once).
When I'm ready to go "home", I walk out of Olivias, and follow the canal toward the main road. After I cross the road, turn left and the first bus stop is a few feet down. It's probably a 3 minute walk from Olivia's. Get on the first bus and it will stop at all the other bus stops and quiet pools.
