If you purchase a season pass early... You'll be happy to know it's a really good deal and you'll have it paid off with your first or second visit. Best time to visit is during Stampede because you won't have to wait for a single line.
Basically go on all your favourite rides with little to no wait... Such as the log ride or the water boat.
Overall, Calaway is a fantastic place to take your kids... They'll love every moment. Prices are good and rides are great for the little ones!
