The more friends that you can make, the better. As long as you are safe and feel comfortable, there is nothing wrong meeting friends. Start dancing, singing, or having great conversations with people you meet along the way during your travels. Just remember that the friends that you have now, were once strangers to you.
Reach out to the local people who live in your destination or other travelers, and you will have an even richer travel experience and make new friends, too.
