I don't think either is truly a 2 day park. I do go to each twice when I am on a long trip, but it is just to do everything again, and maybe just 1 or 2 things that I might have missed, but you can truly do everything in 1 day for each park. If AK has an EMH evening, I like seeing the park after dark, there isn't a lot to do, but to see every thing in the dark is very different. And I hear EE is great in the dark. Haven't made it yet in the dark. Maybe next time. I would call them 1 1/2 day parks. I didn't help, sorry.
