I went to the park with my daughter Friday. We rode Ice Breaker x2, Mako x2, and Kraken x1 and all were walk-on or a station wait. When we arrived at Manta they were advertising a 60 minute wait. I hadn't purchased QQ in advance and really didn't want to shell $30 x 2 to save time on Manta. I decided to ask about pricing at the nearest spot selling QQ. The cashier said it was $14.99 and that it was unlimited but didn't include icebreaker. When I paid, she asked if I had a membership. She scanned my pass and the total for two unlimited QQs was $14.99 + tax. Never hurts to ask.
When we got to Manta, they were only sending people with QQ to one side of the station. So it was easy to get several rides in. Later in the day as it got a little busier they were using both sides of the station for non-QQ. The coaster itself is awesome. Probably my favorite flyer, even over Tatsu. We ended up riding Ice Breaker again (10 minute wait maybe), and many rides on Manta and Mako.
