Wouldn't be too upset if they had to close again myself (can't see it happening however). You have to book weeks in advance if you're a passholder and then if something unexpected comes up they won't even move your booking for you to another day in the week, on a weekday, even though there are still regular tickets available to purchase at full price.
Then you see the same annual passholder persons/people turning up several times a week who have obviously just booked loads and loads of days and no doubt have booked others just in-case they spontaneously want to turn up. Pathetic system which has been left wide-open to unfair use by unscrupulous passholders who are minded to do such things.
Basically it's made the point of having an annual pass 'almost' of no use to people who want to decide to go on a spontaneous trip in a few days or a weeks time. Good luck when it's time for the events as people will just book every single day and then decide afterwards which day to actually turn up on.
Not that I'm bitter about this or anything.
