Ah right.
Problem was the cost I think. The overheads with all the technology, wristbands going missing, staff empoyment etc must have been really high.
If a family are spending near on £150 visiting the park, it's unlikely they'd want to spend another £15 on a DVD...especially when everybody has a video camera on thier phone or a camcorder.
For example, the one that I got last season gratis, I've watched it just the once, whereas I've probably watch AT CF-Live videos on Youtube tens of times.
Shame because I like the concept, hopefully Alton Towers themselves will get it up and running and make it more cost effective.
