Yes I agree too - the fake shop part is the best bit. When it's operational.
The main issue though for me is that putting on the headset and trying to get it to work is never simple and seems clunky for everyone involved. I often have to hold the headset up to stop it slipping - I'm sure you can probably adjust the straps etc but it all just seems a faff and you're in a rush anyway. If the headsets weren't so heavy it'd be far more enjoyable and seamless. Far from creating the "magic", the headsets seem to take it away in some respects - the great pre-show, the awesome IMAScore iMMErSivE audio in the queue, the fantastic hanging train, the spot on recreation of a tube carriage - and then you get in and have to put this thing on that weighs a tonne. Maybe in a few years time when the headsets aren't so heavy and tempermental, it could work well, you never know.
