The ticket system with the only option to pre-buy ...

The ticket system with the only option to pre-buy for a specific date is a good idea, but as we went there we saw that the line was 90 min long! In the rain with cold temperatures ...
The problem was then made worse, because they were still selling tickets, which was quite audacious with that length of the line and that weather ... We could not get a refund but that line in the pouring rain was definitely not worth it for us!
