I went to WDW for my band trip last month. We are in Pennsylvania. The band drove down to FL on a tour bus. We left Friday, got there Saturday, left FL Wednesday and got home Thursday. My parents went to Las Vegas. They left Saturday and my dad got home Wednesday night. So they were gone basically the whole time I was. I was perfectly fine. Other than band camp, that was the first time I was away from home. I survived. In fact, I had a blast with all my friends. I say go and have a good time. It really didn't matter to me if my parents were home or not. If they were home, though, I know they would have went down to WDW to watch me perform and march in the parade.
