Saturday 11th July, didn't think it was busy had fast track for some of the rides & didn't wait that long. There were a few foreign student groups but not as many families as we expected - think the engerlish schools didn't break up till the week after.
Sunday 12th July ,even quieter than the day before , had fast track for all the big rides & would do the same again even if it was quiet,this time we worked out what rides we fancied & worked our way round anti clockwise & seemed to get more done than the previous day.
You could return the next day for £10 or for another day up to November for £15 but you need to show your entry ticket - which is a good deal ( our tickets were £37 )
We had fast track parking ( think we paid £16 no sure though )but don't know how busy the main car park was or how far away from the entrance is - don't know if it was worth it but its a minute walk to the entrance & seemed quicker when leaving.
