I am planning a trip to Discovery Kingdom at the end of this month. I see that they have a "Flash Pass" that costs $17.99. Has anyone ever used one of these? Are they worth the money? I have only been here once a few years ago. It wasn't busy then, so we didn't need it. However I don't know what crowds will be like at the end of this month. Anyone have any advice?

I honestly have never seen that park with long enough lines to have to use a FlashPass. I would say as long as you avoid holiday weekends and weekends during July and August, you'd be fine without it. We rarely spend more than a few hours there and usually do everything we wanted to do.

Other than the water rides on a hot day, the only long lines are for the coasters for the most part. Arrive at opening, and you can ride them in the first hour.

A bientot.
