Everything was fine, except the Singapore side. It was delayed by almost hours, and the bus driver was not very much informative.
A Huge thank you to the KL side’s attendant who helped me to find my wallet.
The part in Malaysia after the border was excellent; comfortable seats, good food, drinks and entertainment. Unfortunately, the pick-ups in Singapore used a different bus, and took an extra hour that was essentially wasted time; this aspect could definitely be organised better.
Pleasantly treated by the bus host & captain
