Fellow LI here. Which specific one is it. There are many with names that are very close and they are really basically the same thing.
My ds went to one about diplomacy. I dont know who the guest speaker was. They also had to pick and list like 3 tours they wanted. My ds had his top 3 and didnt get any of them. Some of his roomates went to embassys and said it was so boring as they were not allowed access and only just sat in the lobby etc. My ds got gettysburg, like 13th on his list. and I think he did go to some war college which he thought was interesting and they did the monument tour at night.
His cousin did 2 of them. One I cant remember and the other one was an invite back for the inaugaration which happened to be Obama. It was a big mess. They put them like blocks away in a stadium. The cousin and several bus mates revolted and walked to the real inaugaration.
The rooms and tours, etc. are well surpervised. I think ds had to do some mock thing and he was the allied troop commander?
Basically the only good things were he got to see what it was like totally away from us. He saw this might not be the career field for him (political/lawyer/fbi/jack bauer type etc). It did nothing if you listed it on a college application etc.
So I guess if you have some extra bucks to throw away, go ahead. If not save it for college tuition and books.
Our freinds dd did some medical thing and like it, but also decided that field was not for her.
Best of luck deciding.
