I've been 5 times this season, all during weekends or school holidays, dead every day. I can only speak from personal experience given that the park do not have a queue time monitoring system. Granted, the weather hasn't been great, but it was only horrendous on one of the days.
The fact that the park reduced opening hours by one or even two hours for almost the whole of the school holidays also suggests that attendance is not what they were expecting.
Five days does not make a fair assessment.
Due to Icon watching, I'm up to about a dozen visits this season.
If it was sunny...the park was busy.
If it was wet...the park was quiet.
If it was in between, the park was steady.
The weather has been poor overall so far this season, so the park has been reasonably quiet.
Same as always.
No change is sexy...to quote jah wobble.
