We went to BB three times in mid July all during the weekday. The park consistantly filled up around 10:30 am. If you were there first thing, grab a nice place to sit or lay out (we love the wave pool area) and make your way to summit plummit ASAP. The lines started to get really crazy after 11:00. In fact, the teamboat springs raft was over an hour long on a Wed at 1:00. The double tube ride (I forgot what it was called) had a line of 30 minutes just to get the tube, then the line up the stairs took another 30 minutes. The days were in the mid 90's°, so there were a lot of people in the water parks that week.
