Going by bus really does save on fuel and travel costs. The trip could be much more fun with everyone traveling together and it would allow them to pool resources which would enable them to reduce the cost of food and refreshment.
@explorerx7 Yes that is also one more benefit of going together in group. Yes enjoyment is one of the biggest plus point of this. Going alone is kind of boring thing if we have to travel for long. But if we are together in big group then we can cut down the time without any efforts.
