birth control pill


hey everyone this Sunday I am going to the water park with my boyfriend and his family and I usually take my pill around 4pm andthe park closes at 7pm and I'm guessing we might end up staying there for the whole day. we are waking up early to get there when the park opens, I was wondering should I take my pill as soon as we get there (which is before my usual time to take my pill) or after when we get back because I'm not really sure if we will leave when the park closes or earlier ... what to do?

the pill will be in the car so I won't have no access to it when I enter the waterpark.
