If we went to the park but now are would like to purchase the Seasons pass, will our first day enter fee be taking off the season pass price

More than likely not. Though the season is almost over anyways. If this is something that you would like to purchase for next season, I would inquire when you go for the first time, next season, and ask about their season passes before purchasing a single day ticket. It's so late in the season now, and we live 2+ hours away, we decided to get a one day pass, and are highly considering a season pass for next year

I don't know we only went for the day
