Ooh interesting one!
I think yes, a park can definitely be too quiet.
Thorpe is by far my most visited park, and back when I had an annual pass I’d frequently visit on quieter days. The trouble is, it was occasionally possible to have everything, and I mean literally everything, done by lunchtime with ease.
Fantastic for re-rides etc, but it didn’t feel like a “full day out” if you know what I mean, and it certainly lacked the atmosphere and that buzz you get from a bustling theme park.
I remember going to a very quiet fright nights one year, having arrived at opening time. We had ridden and re-ridden everything all day, and then when the mazes opened we went through all of them several times, to the point that we weren’t fussed about doing Asylum anymore that night even though it was literally “walk on” with hours to go - unheard of these days for a maze.
Don't get me wrong - I look back on those visits with fond memories, and LOVED the amount of rides we could get on, but overall I think it’s a better overall experience when the queue times are around 10 minutes for things.
Queueing a little definitely helps space the day out nicely, especially in smaller parks like Thorpe. It also builds up that anticipation a bit, and forces you to take in the atmosphere and theming around you.
Staying with the fright nights as an example - my favourite ever FN was the year Cabin in the Woods opened. The atmosphere around the park really added to the experience, particularly around Cabin where we spoke to several strangers around the park about the different routes etc that could be taken. There was a real buzz about it that could only be felt because so many people were sharing the enjoyment.
So yeah, as much as I adore a re-riding marathon, I really do enjoy experiencing a park that is alive and visibly thriving. The perfect balance for me would probably be no queue exceeding 20 - 30 mins all day, but the last hour or so having walk ons. 👌🏼 best of both worlds!
