I had a great time, but I was pretty good at the Flying Saucers. Oops, just gave away my age. In any case the best fun is to get a tire that at the start isn't already jammed between other tires. That way you have some room to get up some speed as you ram other tires. The beach balls add another dimension, but I didn't really try to do anything with them other than to toss them to someone else if they came my way.
Having said all that, I wouldn't wait more than 20 to 30 minutes, which means that the line better be really short. I think I timed a single cycle at about 10 minutes, of which the ride part is probably about 2 or 3 minutes. Don't flame me, but if the handicapped tire is used the cycle time is probably 15 minutes. The ride probably has one of the lowest capacities in the park.
