I was last there in September.
I believe the sky tower was something like $4 an adult and maybe $3 for kids.
The extreme zone is the rock climbing wall and trampoline bungee things, right? I remember those being kind of pricey. $7 a thing, maybe? I think you got a deal if you did both.
I was there 2 weeks ago and Sky tower was $3.00 per person and the extreme zone was $7.00 for rock climbling and $ 10.00 for both rc and the tamp.
Hope this helps you

Not sure if you are interested but it is $6 for a tray of fish to feed the dolphins and there are only 3 fish per tray. Not sure about the other feeding booths.
