I think WDW as a whole articicially pulls the numbers up for DAK & DHS. If you consider adding a fourth day is around $35 this is essentially the ticket price for either DAK or DHS. The fact that Universal parks do as well as they do when competing against parks that essentially cost less than half as much, it's pretty impressive. Another big factor is that for most people they consider these half day parks and go back to the others to re-ride some things or do things they missed on the first day at the other park. So it's not that uncommon for the park to get a lot of traffic and turnstile clicks as people come and go for very short periods. Take these parks out of WDW and I very seriously doubt they would be in the top ten parks.
