I would also challenge the immersion - looking at existing TSLs, there is absolutely no consistency of scale. You have Woody and Buzz figures that are six or so times larger than the other toys, who aren't consistent amongst themselves. The "grass" and rides aren't scaled properly, and there's absolutely no effort to give a sense of "huge" objects - houses, bikes, etc. - that could reinforce the sense of the guest as tiny. Are guests meant to be the size of Buzz and Woody? Half that size? It really is a collection of randomly sized recognizable things tossed together, and the result isn't immersion. You COULD make a clever, consistent, immersive TSL with a lot of wit and clever elements (and, hey, a new dark ride), but that's not even what they're really trying to do. It's a very slightly upgraded Six Flags kids land.
