Best guide book for DCL?

[MickeyMinnieMom]

I am very grateful for the info on DIS, and there is some on the DCL site (when it's ACTUALLY WORKING!!), but as a first time cruiser, I still feel like I don't have my arms fully around what to expect!

For anyone who has used a guide book, which one do you like?? Unofficial Guide? Passporter? Other?

Thanks in advance!!
