    After travelling many times with my family members, I went alone to Italy for a long weekend. I traveled by a train and checked into my hotel before exploring the beautiful town. I went out for dinner alone, that meant I could watch people and took in the atmosphere. The next day I went to Lake Garda and took some lovely picture. I then read a book and sat under the sun for a few hours! I had a really amazed time. I think the best thing about traveling alone is you can be selfish and do exactly what you want to. You are in control of your day and fun, but my advice is to take the opportunity to travelling alone. As long as you stay safely, you will have a wonderful time!
