Hi, I would like to confirm the following to plan my itinerary to Wuzhen.

I plan to Xizha after 4pm and then stay at accommodation in Dongzha for one night without exiting the scenic area.
1) Would there be any difference in price for the entrance fee ticket to Xizha if I purchase the ticket after 4pm? I read some forum stating visitors would only need to pay 80 Yuan if they enter after 4pm.
2) If I enter the Xizha area by only buying the Xizha entrance fee, would I be able to enter Dongzha for free after 9pm?

Would appreciate any reply.
