How important is the residential aspect of the talent search summer camps?

DD11 qualified for our talent search summer camp. It is a residential program at a local university (i.e. a 10 minute drive from our house). DD did not want to attend because she thought that a "sleep away" camp should be more exotic -- not down the street. I dropped the issue. One of my other friend's kid also qualified but the family couldn't afford it. My friend proposed asking the camp if they had space and would let our kids go as "day students" -- less cost and no sleep away issues.

I have no idea if the talent search camp would go for this but I would be concerned about the kids being the oddballs. This seems contrary to one of the potential benefits of the camp -- bonding with a similar group of kids. Thoughts?
