Hi. You did not submit any text hints. However, I will try to help you answer this question as best I can.
The best way a ten-year-old girl can prepare to travel alone is to make a list of everything she will need for the trip, before the day of the trip. This girl can make this list using paper and pen, or her cell phone. The important thing is that she writes down the travel schedule and writes down everything she will take in her suitcase and everything she will need on the day of the trip, such as money, documents, water, among other things.
It is important that this girl ask for help from someone older and more experienced in travel, who helps her to organize and give her tips on how to have a smooth trip without major problems.
