Tickets are $2 per ride, and the staff is very friendly. In the row of 3 horses only the two on the inside "jump" and the larger horse on the outside is stationary. If all the jumping horse are full, they'll run the carousal with the empty outer horses so everyone can get a chance to ride.
It was marvelous! I felt like I was back in time, enjoying some fresh air from the back of my steed (except no one was making me ride sidesaddle in a floor length skirt).
