You don't need tickets, but you need to buy food coupons there, that is, cash coupons. You'd better give them MOP. If you give RMB but it doesn't replenish water, you will lose a lot > .<

But I want to tell you that the food there is not so good, and the charge is very expensive. It is better to go during the day, and there are not so many people. If you go at night, it is more lively, but there are many people. You have to wait in line to buy things and eat, and there is no place to sit. There will be fireworks every Saturday during the food festival.
