They have no idea how to manage queues and
Making you pay for an extra monthly membership, on the opening.
Slowing down the process of going in even further, making it impossible to get in in time to see the first parts.
Why wouldn't you open a hour before and let people get in and grab a beer or something ?
The largest room itself is nice.
But the internal policy and the staff are... A bit agressive.
And the extra mandatory 4 for a monthly membership, is not really something that makes you want to go back. Especially if you're not living in the Netherlands.
