If you stay at one of the hotels in chimelong, can u buy a ticket to get you into all theme parks?

I am afraid that there is no such a ticket including all the theme parks. It has no relationship with the hotels.
If you live in one of the hotel, you can buy two tickets for the theme park and get a VIP tour guide. Once you buy the ticket of one of the theme park, you can enter or exit in unlimited times in two days.
