Overall, I had a good experience with Transtar. The bus was clean, comfortable, and departed on time. The seats were spacious, and the driver was professional and drove safely throughout the journey.
However, I was disappointed that after reaching the immigration checkpoint, we were transferred to a regular bus for the rest of the journey back to Singapore. I had paid for a Transtar Z-CLUB coach seat, so I expected to remain on the same premium coach for the entire trip. This change was not communicated clearly in advance, and it did not match the premium service I had paid for.
I hope Transtar can improve the communication regarding coach transfers or ensure that passengers who pay for Z-CLUB receive the service they expect throughout the whole journey.
Other coaches will provide complimentary bottled water for the 7-hour journey, at least the small ones. Good if Transtar can also do the same which is basic for long journey.
