Again, we're slipping back into claiming that loads of rides = a good day out. It does not. It will for some, it will for pass holders, it will for locals it will for many of us on this forum because we've been 100's times. It does not for irregular visitors who come from further afield.
The 4pm closes are due to financial constraints, pure and simple. What we've got this year is now effectively a 2 tier park experience. A theme park experience on weekends, loads and loads of rides and little else on week days. To echo @pluks point, if you take your local/passholder/enthusiast hat off, I think you'd be surprised how many people will not visit simply due to 4pm closures. You absolutely would if you live local or don't have to pay directly to get in, but would you chance it and drive all the way up/down to Staffordshire on a 4pm day ticket if you lived closer to Blackpool, Paultons or Thorpe for example?
Very Unpopular Option alert - mid week closures should return. If the park can't afford to offer a full day experience every single day due to demand, it shouldn't be open. This would limit the choice of day I myself in particular could go on, but it would make the remaining days busier and more cost effective to operate properly.
