Thanks for all the replies everyone . I personally found R&R a great system, no queuing at all on my last visit. I can however see the counter argument of those that don't use the system, having to wait longer in the queue. However that isn't a flaw of the system, just people not wanting to use technology or not enough communication of the system by Merlin.
I'm not sure on everyone else views, but I definitely see a future with no queuing necessary and a well made application that can do everything, from tracking live times to booking into a queue for a ride and perhaps also being able to contact staff via live chat easily within the application - say to ask whether a certain ride is closed, ask what the hold up is with a ride, or to check on something quickly - would definitely improve customer experience.
I feel that Merlin aren't willing to invest in these type of applications or technology improvements however... I mean even the mentioned attractions.io built apps above look a bit half hearted. It looks like a company has made just one app and will rebrand as and when necessary to be honest.
Does anybody know, whether Thorpe Park support contactless payment throughout the park? - I assume so, will be wanting to leave the wallet at home on my next trip and easily grab a drink with the apple watch
