Is it comfortable and recommendable?I've travelled on night buses and while I think they are comfortable and would recommend them, it really depends on how the individual traveller. The buses are dark and the seats are typically separated from each other, but if you can't sleep on buses then you won't be very comfortable as its a long trip.
Do they buses really stop every three every hours for rest?
Yes, the buses have prescheduled stops at rest areas where there are restrooms, vending machines, convenience stores, and sometimes restaurants.
