We stayed at the Kalahari for a night after a Christmas party.The room was clean, but very average for the price. Two queen beds, refrigerator, microwave, average sized bathroom. The room was dark and the view from the window was the outside wall of the waterpark. There are plenty of activities within the resort including the waterpark, indoor amusement park, shops, places to eat, and a coffee shop. There is also a large movie theatre on site.
We had a bit of a tough time sleeping as there were lots of kids running and screaming through the hallway into the wee hours of the morning.
If you are looking for somewhere to take your kids for a weekend in the winter to enjoy a waterpark, this is the place for you(a little expensive). If you are looking for rest and relaxation, try the Sundara Spa resort at the Wilderness.
