If you want to take a tour of Martin Luther King Jr.'s birth home, check the national park's website for availability.
Lottafrutta opens at noon, so plan accordingly if you want to get one of their famous fruit cups. We were ready to get one as a late-morning snack, but had to wait until they opened.
The middle of summer might be too hot to walk around the park. We visited on a mild December day, and the weather was perfect.
Entrance to the Martin Luther King Jr. National Historical Park is free.
