How much does the People to People cost?

I just got a letter from People to People today...again. This is my 4th letter. In previous summers I got letters to go to China, Austria, Australia, and some other places with those trips that I forgot. Each year I've talked with my parents, and they said they really wish they could send me on the trips, but its probably too expensive for us. This time, the trip is to England, France, Germany, Belguim, the Netherlands, and Switzerland. Tons of really cool experiences, I'm sure. Its been my dream since I was really little to travel all over...but especially all over Europe. There's so much history, and seeing all the different landmarks and experiencing different cultures would be absolutely amazing. My parents and I had another talk about THIS trip, but this time the answer really hurt. I'm wondering how much it costs, if its worth it, and possible ways to do fundraising or something of that sort? Thanks in advance!
