Ask about women's organizations. Trust your intuition and feelings. If you are offered a ride and you feel some anxiety, decline the offer. If you are in a setting that makes you nervous, leave immediately. Don't be persuaded to do something your instincts warn you against.
Precautions also apply to social situations.
Most likely, you will find everyone you meet to be interesting and interested in you. However, you cannot make judgments about your safety based on another person's looks, appearance or financial status. Only you can determine how best to handle a situation. However, if you prepare yourself before your departure, you will find that you will have more options for dealing with situations. Don't be a victim.
