Family is coming in 2 weeks

I am not sure if this in the right forum, but, I have my Uncle and Aunt coming in two weeks, and I am really excited to see them, but I don't like having people stay for a long while at my house, and they are going to be staying for a week. I also have to give up my room, which I am really stressing over, because they are 3 hours ahead of my time, and because they will goto bed way earlier than me, I won't be able to get into my room to get stuff I need. I also just don't like the idea of them invading my room and my personal space. How can I get over this?
