I went alone to this experience, and It became one of the most beautiful experiences in my life. At first, I was insecure, and I have to say that at some point, I doubted myself if I was ready or not, but I definitely overcame a lot of fears. Also, I carry a lot of friendships around the world and a new language in my bag (I didn't know anything about the Italian language), so yeah, don't think twice if you feel like it.
