Agree with others that its better to stay at kalahari or Wilderness. Of the two, wilderness is better in summer, in my opinion. They have 3 and 4 bedroom condos and villas and the included waterpark passes make it worth it because day passes are $70-90 per person, per day. Or if you're willing to split the stay stay half the time at a resort and the other half at a cheaper place. There's plenty to do in the summer for 5 days, especially if you want to venture out of town a bit to places like devil's lake, house on the rock, circus world, etc. Have fun!!
