If you are printing off your documents on line and you do not have
DCL transfers, the only thing you need in the entire documents pack is the luggage tags. If you have DCL transfers, your transfer coupons will be in the document book.
WHen you say that you have 4 "little books," are you talking about the information books--what to pack, gifts you can buy, shore excursions, etc? Or are you talking about the document book with the cruise contract? There is NOTHING in the information books that yo need after you look at them (these are the ones that look like they are put together with hair ties). I'm not sure why you have 4 document books unless you booked 4 cabins.....that booklet is actually rather small and I usually bring it along even though I know I don't need it.
