we are coming Dec 26th-30th and I already bought my tickets online, are they good for whenever we come and what if there is a price change?

Any lantern tickets are good for any day. Water park season passes are not valid for the lantern festival

Just for clarification, none of the water slides are open during the winter months, it's only open for Festival of Lanterns right now. I am not sure if your online bought tickets will be good for any day as stated Dec 26-30th, 2021. If the tickets don't have a date of use printed on them, then it's possible you can use on the dates stated. It's probably best to call the parks office and confirm it. There is a live act nightly at 7pm, don't miss it 🙂
