I agree with the all worlds, except LWM, are in one universe and it is supported. in Agrabah-EF, a merchant wished Cyrus as far from Agrabah as the Earth is from the Sun (~93 million miles). It lands in Wonderland's maze. Wonderland is also noted as being a small world by others.

The Hat can only travel to magical worlds, just how the White Rabbit can only travel to magical worlds. The only definite way to travel to LWM are magic beans and the DC. The shadow is a bit of a plot hole since why could it exist but the Chernabog not?
