First time I came here they were closed due to lightening in the valley. I didn't see any, but I suppose it's better to be safe than sorry. I highly recommend calling ahead if there's overcast. I came back another day when they were open. It's $20 just to go to the observation deck, and while the views are stunning, it seems absolutely pointless to me. Maybe better at night. As for the rides, Big Shot was my favorite. It rockets you up and down the steel tower on top of the building. Next was X-Scream which rocks you back and forth while picking up speed over the edge of the tower. If you can afford to wait, I'd recommend waiting to be able to sit in the very front row as the seats in front of you take away a bit of the thrill of rocking off the edge. Still very exciting without being in the front seat. Lastly for me was Insanity which was a claw like ride that spun in a circle while you faced the ground below off the edge of the tower. I hated this one as it made me dizzy the very moment it began spinning. The other two were great. I would give those a go.
