for our Honeymoon and LOVED IT!!!!!!!!!!!!! So much so we rebooked another cruise with them for their Mariner of the Seas while we were still on board. I don't know of any books, but you really don't need one. Go to cruisecritic.com and go the
Royal Caribbean boards as the other poster mentioned. Also go to theknot.com and the honeymoon boards either do a post for the adventure or do a search for the adventure and
RCCL, tons of people are choosing RCCL as their honeymoon of choice right now on there and you will find tons of info as well. Also cruisemates.com has some great info. Of coure there is also royalcaribbean.com any ship that is in the adventure class will be helpful. While on rccl's website you'll be able to tell which are her sister ships (which I believe are the navigator and mariner), you can also book all of you excursions right on their website rather than waiting to board which is a wonderful thing. If you find that something is already booked don't worry though, they hold spots for onboard passengers (here's a hint though, don't wait for the excursion desk to open, just go directly to your cabin and turn on your tv and go to the rcv channel and book your excrusion the minute you board, this way you are ahead of everyone who waits for the excursion desk to open and you don't waste time standing in line). If you have any questions just let me know! We only have 11 months until our next RCCL cruise any can't wait! Now we are just trying to decide if we want to do a disney one as well. (that's what brought me to this board). We are such RCCL fans it's going to be hard to ever leave them (as much as we love Disney its going to take some serious convincing).
Really though, don't worry about not having an adventure specific board, you don't need one. Also, if you want a cruise book (which you really don't need for RCCL) pick up one that's general to where you are going, ie Eastern Caribbean.
