I've never heard of QQ selling out before the day of, though I imagine they may sell out during the day, ie if you are going afternoon, they could sell out by the time you got there. It is generally NOT recommended to purchase QQ ahead of time by those here, as it is specific to day, and you may or may not need it, etc. Having said that, we just came back from staying at the Spinghill Suites @ Seaworld, as a partner hotel, we got the unlimited QQ bands for free with the stay ($104 per night, loved the hotel too). It was moderately busy for Feb time frame, certainly nothing like spring break busy, but we really loved having the QQ, as it allowed us to literally ride Manta in the back row (which is the BEST for thrill position on this coaster, it YANKS you through the loops, etc there!) 4-5 times in about an hour, it was wonderful! I am sure they will have them, just probably not open for them yet. Have a great time!
