Although the ticket price of 94🎫 is not cheap, you can enter and exit the village unlimitedly for three days, which is quite suitable for a short stay to see Hongcun at different time periods.
Regarding food, I recommend the "Nanhu Qiyuanhu Restaurant" at the entrance of Nanhu Lake and the "Zuiyuetai Hui Cuisine Restaurant" next to Yuezhao, because you can sit on the second floor to see Nanhu Lake and Yuezhao.
Regarding accommodation, it is up to you to choose, just stay in the scenic area.
In short, four words, you must "take it slow".
