Depending how many people, sharing a private ride might make sense.

$2200J each way per person for the bus is great for a single but for 3 or more....that's near $40 US pp. So $120. So perhaps approaching what you might pay a driver. You'll need a taxi IN town also, or plan to do buses, and that's on top of the bus fare.

Plus private will be faster. Ask around, maybe someone knows a driver who has business there and would be willing to take a reduced rate if you work around his schedule...
