Where to go in Acadia national park?

My wife and I are taking our new camper up to Acadia national park. We are traveling from Cincinnati Ohio for a 8-10 day trip. Where are the best places to go and camp. I am taking a 3 year old boy and a 4 month old daughter. So it must be family friendly.

I am planing on taking Tons of pictures. We love nature hikes. Water, alot of out door stuff. I know this is vague. We are going last week of june, first week of july. Any info you can provide would be great.

Thanks
