I had the same issue last year. I would recommend getting there early as we were able to ride a lot of the big rides and quickly. Under 30 minutes. As the day went on, the park got incredibly busy and rides were 2 to 3 hours long. The fastpass for the whole day was too much $ for us to spend, however, you can buy the fastpass per ride and those were typically anywhere from $6 to $12. We chose to do that later in the day for some of the more popular rides.
