Belgian newspaper article from this weekend:
Translation of the relevant parts:
We went to amusement parks en masse during the easter holiday because... there were already many people there.
Why we go to amusement parks en masse despite the long queues.
... So you were warned about long queues, in case you still went there this weekend. And yet we didn't let that stop us.
"People like to be where a lot of people are" explains leisuretime sociologist Ignace Glorieux. "We want to seek out the masses because we think there is something to be experienced there. So we want to be there too."
No, of course you have no desire to queue for hours before you can go on an attraction. "But it does make it more special to have to wait for it for three quarters of an hour" says Glorieux. "We are part of something that is wanted by a lot of people. It is as if waiting long makes it more precious."
The sociologist compares it to a concert: we don't want an exaggerated amount of people around us, but in a half empty concertroom you feel like you are somewhere that has low interest.
"At the coast it is just the same. If it's calm there, a lot of people complain because there's no atmosphere. It feels weird when there are too few people. We then miss the holiday spirit."
So remember, if you had to queue a long time this weekend to be tossed around in an attraction for only two minutes. Not queueing had probably made it less fun.
