And even if they did, they would just be constantly doing stuff all the time. That becomes exhausting, and you can't enjoy everything. I go for a week minimum, but usually longer. I like to have a rest day after a few days of the park. Then do another 3 days. Then relax for a day or two before heading home. Makes the trip much more enjoyable when you're not trying to squeeze everything in. Nothing is worse than being tired, cranky, and miserable at a park. You spend a ton of money on these trips, you want to enjoy yourself. I usually go once a year, and that's how I do it. Any other way would be miserable.
