We were at Disneyland Paris in Febuary and I could not find much in the way ouf guide book until I arrived at the park. So before we left I ended up getting a couple general Paris books at the local bookstore and they each had about 20 or 30 pages about DLP in it. I'm sorry I can't remember the names, but they were also available on Amazon.
If anyone does find something for Tokyo (with DisneySea, once it opens) please let me know. I am trying to convince my traveling companions that we could convievable visit 11 theme parks in 14 days(WDW, DLR, TDL, and then Knott's, Magic Mtn, and LegoLand). Guess I should just stand up and introduce myself...
G'day mate ! I've been to dreamworld ! It was eeriely like DL
there is a series of books called "take the kids to" and they cover DLP well. The other thing is to bob over to the UK board and just ask questions. They are experts.
