Look at the pictures below! I surely will not mind traveling in such transportation. It looks really cool and beautiful. They offer services e.g., transportation to-fro from airport and you can even book the bus for a few hours of meeting. I guess if this kind of bus is available in Singapore, it will be a good choice for fellowship.
