The acoustics of this room are dry, little noticeable resonance of the building and the stands themselves, so very good. Whether the sound is good then depends on the skill of the technician, but that usually remains a matter of taste and / or perception.
My seating experiences are different. If you are sitting close to the stage above an entrance, you have the chance that your snout is behind a lamp that illuminates the stairs and you have to look around it. Too bad, because in themselves those are very pleasant seats. And it seems to me that it is quite easy to do something about it by the technical staff.
For a concert with a normal stage at the front (back?) Of the hall, I think the seats directly opposite the stage on the 1st floor are the best place. Binoculars are useful without video screens.
And yes, it has been said and written a lot, but the Ziggo staff really should do more to keep the people in the stands. I don't mind if people stand short for me, but apparently there are a lot of people who buy an expensive to very expensive seat ticket ... and then stand up for the whole concert. This is very annoying for the people behind it, where a large part of these have bought these expensive tickets so that they do not have to stand. And sometimes people cannot stand for long due to physical discomfort. You are nicely done with that. In the Horse in The Hague, the Cock-Not-Lollipop was introduced against the endless chatter during a concert (even so incomprehensible that you will go through the holidays together for 50 or more and at the same time spoil the pleasure of others) . I propose that the staff at Ziggo Dome (and preferably in other concert halls) be equipped with Stay-Sit-Brownies to hand out if someone stands and stands in the stands. If one has not yet understood the message, then take the culprit away. I mean this really seriously, because not only me, but many are annoyed by this behavior.
I also regret that you have to leave so quickly after a concert. You just took your belongings out of your locker or went to the toilet and then want to have a drink, but you are delicately told that the tent is already closing. Of course, I understand that every hour extra is an hour extra pay for the staff, but could it perhaps be a bit more customer-friendly? Nice if you can exchange a mountain of coins again, but you still buy those things to consume? Not everyone wants to go to the usually packed Club Ziggo, but it seems that the intention is to go there.
With some minor, but important adjustments, it is the best and most customer-friendly mega concert hall in the Netherlands. But it is not that far yet!
