I also had not thought of this book as similar to Alice at all, I had not really thought of it as a children's book at all, but I suppose that term has come to mean something different than it did then. One commonality I noticed between the two that I don't think has been said yet is that the whole story starts in both novels by our protagonist following someone into a strange land and thus beginning their adventure; Alice with the white rabbit and Kim with the lama. And they are both on a quest to find something, at least Alice is in the second book with her journey to Eighth Square and Kim with the Red Bull.
That's about all I have that wouldn't just be repeating what others have already said, but I really enjoyed reading everyone's posts about this topic.
