The thrill to price ratio for this activity is considerably lower than a Magic Mountain or other Theme Parks. If you are someone that doesn't do these "crazy" things often, this should be a thrill worth the trip for you, provided you aren't on a tight budget.
They have some of the longest lines I've seen. Friendly staff and if you go when it isn't too hot, kind of a nice trip to get outside and do something.
But if you are someone that loves thrills (roller coasters, performance driving schools/hot laps, bungee, skydiving, etc. etc.) you will not find this very thrilling. Save your money.
5 stars if you are easily 'thrilled' 3 stars for fellow seasoned thrill seekers - average = 4
