Technology is a great help but do carry printed map along and share with all your group members. It will be easy to see routes and go according to it.
As you are in a big group, order different kind of dishes at a roadside restaurant. By doing this you can taste a different kind of dishes and even it will be a fun to try something which you have never done.
Be friendly with your group and tell them how much you can travel and what speed. Don’t hesitate about asking for breaks in between as it is quite important otherwise you might feel tired and feel sleepy on the way. So be careful about this.
Take the tools along as you never know when the vehicle can stop working. Maintain cordial relationship with people so that you can also ask for help when needed.
