I was worried about the same thing too during my son's first year at TIP camp. I had to pay the balance of his homeschool class tuition while he was gone and I was a little worried that he'd come back wanting to go to a brick-and-mortar school. He came back totally recommitted to homeschooling. I think he saw how good he has it!
I just picked him up from UGA for his second year of TIP camp. Once again, he absolutely loved it. He participated in the Criminal Law and Mock Trial class where his teacher was a lawyer with 36 years experience as a criminal defense attorney. She brought in a lot of guest speakers: judges, public defenders, George Zimmerman's defense attorney, a lawyer who has argued in front of the Supreme Court, etc. He learned a lot and benefited from his teacher's encouragement that he has the brains and temperament for being a lawyer.
The social aspect was great for him too. He got to spend three weeks with his intellectual peers. It was a breath of fresh air for him to make all the witty jokes he wanted, knowing that the people around him would actually get them. :-) They keep the kids busy during the evening with things that interest bright kids. And for a growing boy, a college cafeteria with unlimited food is heaven.
He's already talking about next year. He has to decide if he wants to go back to UGA or head to the main campus at Duke. Decisions, decisions.
