Take cell number of bus conductor. In case you miss the bus at any stop then it will help you to track him or catch the bus at next stop.
While getting down from bus at an intermediate bus stop, always ask the conductor about the break time and come back at your seat just two to three minutes before.
Bus journey gets more comfortable in large groups because you spend your time in talking to your known ones. Hence if possible try to get people along with you during bus journey.
