Interesting that SnapFish do the direct onto acrylic printing - will have to remember that, Whitewall only seem to do the regular print bonded to acrylic (unless I've missed something).

I have had acrylic blocks done by another company, and there is definitely a thick kind of paper/card stuck to the back of the block. (there was also dust between the image and the block, causing an air bubble).
