Plan ahead and buy tickets online. If you have your eyes set a certain theme park, sign up for their newsletter. Sometimes you can find exclusive deals with lower prices. Also, it’s cheaper to purchase tickets online rather than the day of. Another thing to take into consideration is whether or not it will be cheaper to do multiple day tickets as opposed to one day tickets. Some theme parks are so big they can’t really be covered in a day so you may benefit from this and pay less for it as well.
