Will the park be open on Easter this Sunday? I just want to make sure because my family goes every year and some family members have told me that it's going to be closed.

Yes, They host an annual event for it

Tbh it will be open and there will be activities for you to do with your family!

Yes and they have an Easter egg hunt and games for the kidos

Per their website the park should be open with some special events. You can give them a call to double check.
