You made yourself look a bit stupid there by firstly saying their "testing" then saying its "temporary".If it works out good, THORPE PARK are most likely going to stick to this as opposed to the older way of queue boarding.In my opinion its a more reliable way of telling queue times, firstly using the old method, lets say " SAW: the ride queue time is currently 70 minutes", and you queue for it only to find out its 90 minutes, some people are going to be really p***** off they had to wait an extra 20 minutes, by giving a rough time within a certain time gap its then saying it could be anything between these times. 60+ is better, then people can prepare to wait for more then an hour, you might say differently but I hope it stays!
