hope this helps:
Shanda seems more willing to jump through hoops than Brianna was...and she makes sure to fully explain things, etc. I haven't yet had my ceremony - but my
travel agent talked to the people on board and for some reason they already know about my December wedding! WEIRD! So, it sounds like they actually get some info ahead of time and not just later in an email from DFTW. There are special requests I had like a specific drink type to serve instead of champagne at the Cake and Champagne Celebration and she said it's the same fee as champagne is, just charged per person - we are having 40 guests. I also asked for maybe a fruit platter to pass around - again, charged per person. You can choose to have the C&CC onboard or on the island - but on the island isn't as organized and nice as what I was told by Shanda. Just call Shanda and ask her and she will perfectly clarify things for you : ) I have noticed that they have changed certain aspects of the weddings over time, so you just need to check with her for current info.
They send you a package (elements and enhancements) where you choose from 3 cake "styles" and 3 bouquet "styles" - the flowers types can be SLIGHTLY modified - for example I told her I HATE callas and they said they will use more cymbidium orchids instead (tropical bqt). The bouquet colors can be modified easily though you just tell them what colors you like. Because of the required longevity of the bouquets for the sailing (since the bouquets are designed in Orlando) they only do specific types of flowers that will last - orchids, callas, roses, (hardier blooms as opposed to softer, delicate types). The cake comes in three styles because there isn't an actual cake professional on board - they are trained to know only the three styles.
(hope this helps!)
