Well, we were there in July, so it was very hot! Use a bus that is free of charge. It's a lot of walking starting from the visiting center to the 1st residency house.
Not sure if it's due to covid and there're limited places to visit, but in general, the idea is the same, it's a residency: the house, the garden, how they made the dyes and woven clothes/blankets, how they preserved food at that time etc. In each house, the workers are dressed in costumes of that colonial time and answer your questions.
There're some cafes and restaurants open only after 11:30am or later on merchant's market or on cross streets. Shops and boutiques were mostly closed.
In general, it was very tiring for us and educational maybe for my 10 year old.
We loved the American Revolution Museum at Yorktown so much better; it was much more informative with the outdoor area with workers in costumes: the Dr, the shooting officer etc. Jamestown Settlement was nice too: it has a museum and an outdoor little areas with workers of that time commenting on their jobs as well.
Due to covid, all 3 areas were not crowded at all, so it was worth going! Otherwise, the lines would be impossible to handle in 90F.
