Just to confirm this works perfectly! I simply scanned my pass and printed out a copy. Used it twice to get a locker as I had to go back and get someone else's stuff out. I'll probably print out a few extra copies and keep them in my wallet for this.
As far as the ride it was great. It didn't seem any smoother or rougher than before, any difference to me was very marginal. I sat in the front row didn't try out the back. The queue was nice. Overall it's an improvement, just not a huge improvement. My biggest complaint is the sound. The speakers are mounted in front of your feet so obviously when you have wind rushing past your ears your not going to hear it, it's a shame they didn't put them in the headrests.
