Anybody and every one please help!?

My mom and my sister are going on a week long trip to yellowstone tomorrow and the weather is going to be just how I like it. I'm not going my mom said that if I wanted to last minute I could but here's the thing I can't miss school It is just to much work is there anything I would be able to do or should I just not even go. My dad said that this is probably going to be the last long trip I will be able to go on because I am a sophomore graduating early. Please help 10 points!!
