They will be open, but I don't know how much fun it will be if it's raining. If there is rain in the forecast for tomorrow, I don't know how much fun it will be for your family. Perhaps you should consider going another day.
They are open every day, keep in mind do not give refunds. If you and your family coming it is raining and they have to shut down the park you will not get a refund so you may want to choose another day. You should check your weather for the day and look at the rainfall totals for different times and see if it's worth it. It is a great amusement park. Have fun
