If a girl is willing to travel with me alone, can it show that she likes me?

If a girl is willing to travel with you alone, then she is likely to like you or have a good impression on you.

Because friends of the opposite sex travel together, they may get along with each other day and night, and even have some ambiguous relationships. If she knows that you still like her and is willing to travel with you alone, it means that she is ready to associate with you. In this journey, you must be very considerate and careful, so that girls can feel your love for her.

There is a great possibility that after your trip, you will be able to establish a relationship and become boyfriend and girlfriend, so seize the opportunity.
