By bus:
Buy tickets the day before you plan to travel.
Make sure also that you arrive at the bus station a little earlier than your departure time.
Take enough food and water for the long journey. Fresh fruit is also recommended. The driver will stop the bus roughly every two hours to allow passengers to take a rest and eat at some of the nearby small restaurants, although the quality of the food is sometimes not the best. If you are traveling in the harvest season, it is easy to buy some delicious fruits from roadside vendors. If you are buying from the roadside, don’t forget to bargain for a reasonable price.
