Well this is not exactly a new thing. If it was a one off then I'm sure we would all understand. However this keeps happening. Multiple rides not being ready for the start of the season. The chance of 4+ rides having a last minute fault year on year is incredibly low. Besides most parks scheduling accounts for delays like you mentioned. Something clearly isn't as good on the maintenance side as it is at other parks. Could be bad management, lack of staff, ageing neglected rides, the list goes on.
