When are you coming? I always think Kalahari is a better choice in the winter. There is one indoor park, so you are not shivering up and down hallways or outside to to to another. In the summer, it's a horse apiece for the most part for kids of that age,

With kids that age you won't go outside to park #4 at the lake, its only for little kids, the others are connected by indoor heated walkways

But there is still a lot more walking in the wet swimsuits than you will have at Kalahari if you go from one waterpark area to another.

I have been to both recently and with kids your age would choose the Kalahari without a second thought. You will be much more comfortable their and no mile walk to get to your room.

We like wilderness the best. We like the ability to head to another park if one is kind of busy. We have stayed in the wilderness and in glacier canyon and have never thought that the walks were very long. Maybe we are just more mobile or less afraid to walk as a lot of people on here say it is too much walking there.
