<human>: Can you provide a brief overview of the text?

Okay so I graduate high school in like, 2 weeks, and this summer I want to go to Anime Expo in LA. I've been before, 2 years ago, and stayed in a hotel with my mom. When I went, a long time friend of mine from WoW was also going, and was the same age as me, so I met up with him and spent most of my time at the convention with him, but some of the time alone. He also conveniently was staying in the hotel across the street from mine. I told my mom that I had met him at the convention itself and made friends with him, and she was fine with it. My overall impression was that the safety level of the convention was very high. There were so many people around that I never really felt 'alone' even when I was. I'm a very paranoid person, I don't even like going out in my own suburban neighborhood at night. And I was only 15 at the time. But I never felt threatened or paranoid during my time there.

I made plans to go again this year, with a friend, but she had to cancel because it conflicts with her trip to Europe. I still want to go though, and because I've been to the convention before, and been to downtown LA many times before, I feel comfortable going alone, with caution. I would confine myself *strictly* to the hotel, the convention center, and the shuttle that goes to and from these locations. I wouldn't go to any of the late night events like I did before, just to avoid returning to the hotel late at night. I feel like this is being extremely cautious, maybe too cautious, but I'm not a stupid person, I don't want to get myself into trouble. 

Nonetheless, I am 17, and even though I'll be paying for it myself, I can't actually stay in a hotel without my parent's permission. And they don't think it's safe. What's your opinion? Are my parents right, and should I not do this? If they are wrong, what are some ways I can convince them to let me go?
<bot>: I'm 17 and want to stay in a hotel by myself, my parents think it's not safe. Are they right? If no, how do I convince them they're wrong?
