$25 locker rental on a quiet evening and i made it on 2 slides in 3 hrs. Its not worth it. On the raft slide people were standing at the bottom holding all the rafts and chatting while the huge line waited. On the tube rides each only had 6 or so tubes for everyone and others were pushed to the side not being used so huge lines and waiting for people to climb the stairs. All-round just go to a pool with a slide so you can go down several times. Also, several slides were out of service. When walking through the park i noticed several rides also were. Security wasn't even checking bags at the entrance. They seem very poorly staffed. The comments about waiting a long time for a 30 s slide seemed accurate to me. Muskoka plunge had one girl up to top and a long wait between sliders. And people kept cutting in line all over the place, but there were no wonderland employees around to do anything about it.
