One will not recommend it, but many on CC love it for the price.
Okay, let’s give facts about the $2/2.50alleged public bus (private minivan- aka Jintys)
Off ferry at Midtown, down pier, walk to main road (Front Street) turn left down Front Street, turn 1st right, walk down side street, at main T junction you’ll meet Back Street, search up and down Back Street for a Jinty with a sign in windscreen for the required destination, board, wait until full before departing.
Journey will encompass on/off main roads, stopping to drop people off and pick-up.
On arrival at destination agree where the best Jinty pickup point is for regular passing Jintys for return destination.
Returning one has to stand at the pickup point, view from distance/search the windscreens of approaching Jintys for the destination sign required, flag down the Jinty, which may not stop if full.
Repeat until one stops, board. Arrive at destination (Back Street)
Note the time taken to arrive, from the time one left the ship, walked to ferry, queued, paid, queued, boarded, sailed etc.. to destination. Then allow an extra 30 minutes minimum for the return journey for flagging down and heavy port traffic.
