Hi Joy,
It depends on how many of Weng guests are attending on the 23rd. But I don't think you need the P/T until 2pm. What time is Khun Nick's party? You will need P/T for that so the Mgr can work as party host with a shadow.
Again, all the P/T staffs need to fulfill their on-site park training (FD+JP) whether we have customers or not. They all need to be ready for when we have customers.
I think we set it at 7-10 hrs depending on their ability to learn the park skills. Pls check with Na on the hours for park training.
