You're comparing them to the 2 least popular thrill rides. Whereas wicker man or smiler are busier usually than any of those cbeebies queues
At the time I checked Wicker Man was Closed and The Smiler was on 50 mins so only slightly longer than Octonaughts. I'll leave you to do the calculations as to how much more money The Smiler cost the park to install than Octonaughts did
The point I was making earlier was most of the rides at Cbeebies were on zero minutes if you looked at family ride times they were green 0 minutes apart from octonaugts, postman pat and in the night garden (that's only 3 rides out of cbeebies)
How many rides do you think there is in Cbeebies??
Octonaughts, Get Set Go , In The Night Garden and Postman Pat all had long queues.
Justin's House and Charlie and Lola are not actually rides.
That only leaves Peter Rabbit which was closed, NumTums which has never had a queue even as Doodle Doo in the farm and Go Jetters which is the odd one out here as I have never seen it without a queue so not sure what was happening yesterday.
This is ignoring the fact that Cbeebies has 5 very popular shows and a large play area not included on ridetimes.
I spend more time in Cbeebies than any other area of the park and can tell you for a fact it is extremely popular and always busy.
