Over $100 after sales tax just for a single day pass (which is a good deal more expensive than the average cost to get into similar parks in other states), just so you can spend 90% of the day standing in ridiculously long lines at almost every ride.
The Ogden-SLC-Provo corridor has more than enough people to warrant another amusement park. I'm not saying Lagoon is bad; it's actually got some great rides, but it's overcrowded and overpriced because it's the only ticket in town.
