Pros: Cleanliness, on time arrived destination. Comfortable journey. Cons: So far it is good. Tips: Yes , make double sure with staffs from the stand in which gate you should stand before boarding the bus. Still staff can misguided you in choosing the right gate even you show them the ticket. You are standing in wrong gate and line and later you have to rush and carry your heavy bags to the right gate as soon you know that in last moment of departure.
