summer vacation plans

I will go to the U.S. in this summer. It is school home stay program. I will stay American home. Each person has an each family. I think it is a little difficult for me to spend every day, but I can speak English a lot. It becomes really good practice. My host family has four members. There are a father, a mother and two girls. I'm looking forward to meeting them. I want to know American culture and let them know about Japanese culture too. I want to try anything what I can do in this summer. I don't want to regret.
