Decided to opt for both tours up and down the river. One way is 10 and both is 17. The staff was friendly and knowledgeable. The trip lasted 50 minutes each way. Boat was well kept and had clean restroom on board. Is great for the whole family. Now the down side. Do not go if it might rain because when they close the boat windows it gets hot fast, also go when the temp is cooler for obvious reasons. Will go again.
