Ah, apologies, but yeah it's 10am - 8pm next weekend.My advice would be to make sure you get on everything you can, there are lots of great rides at BPB including Valhalla & The Big One, the four big wooden coasters (Wild Mouse, Grand National, Big Dipper and Nickelodeon Streak) and the dark rides, as well as the other coasters and flat rides.
Also, if you get there for 10am it is worth noting that only a few rides are open until 10:30am, but I would recommend getting on Nickelodeon Streak first (it opens at 10) as the queue can get very long later in the day due to it only running one train.
Hope this helps.
