Olympia Looping was a good solid ride but not worth the hype in my opinion. It was a very odd experience where I felt as though it was fun rather than thrilling. To put it into perspective I personally find TH13TEEN much more thrilling. Also the restraint system is very flawed, due to the forces experienced on the ride the shoulder restraints seem to slam down onto your shoulders if you aren't careful, leading to a fairly uncomfortable ride. It should also be noted the forces experienced are reminiscent to an enterprise as opposed to something like The Smiler, so for those who don't enjoy that feeling - you have been warned!
It's definitely a great travelling ride and I'd like to see it return, however it by no means stands against a large amount of the permanent coasters in the UK and at £9 a ride, I wouldn't pay twice!
