KK3 was amazing espically some insights into some of the rides. I was also at first intrigued by a character that I thought was going to be "bad" but I was wrong..I personally think the 4 book will end up on the crusie ship because in the third book it mentions that the company has already made up its mind and will inculde the DHI'S into the Ice skating shows as well as the cruise line. and that pretty much sets up book 5 where they are headed for an ultimate showdown between the kids and the baddies.
