Thought can do a cheap getaway via Senai. All the way to Senai use public transport too. But sadly....after SG checkpoint...there just swamp of people....queue for bus...literally stuck there until my flight time. The human jam is much worst than last I use this route 10 yrs ago. Missed flight....
Never ever depend on the public transport in JB.
The bus system is poorly planned and executed that come complete with poorly maintained buses, many of them are already falling apart.
The newly located bus terminal below the JB CIQ is a typically classic chaotic zone.
The area is just far too small serving too many buses and worse, the roads into and out of the terminal were perpetually lined with illegal parking on both sides of the roads.......and never you'll see a traffic police there to control (they are probably busy elsewhere collect traffic summons). A bus can easily need to take 15 to 20 mins just to enter or leave the terminal.
And for the taxi service, unless you take one from the CIQ where you buy a ticket for your journey at the counter but elsewhere, you need to haggle the price with the taxi driver and describing your destination with a non English speaking taxi uncle can be a nightmare.
