Okay,I'm jumping in with my two cents:
Last year, the Fantasy MV was my first time doing an FE and it was true trial by fire, as I had, I believe over 100 cabins. Having only 30 cabins on our 3/9 Fantasy trip is a true vacation! So last year,as overwhelming as it was, I did what I felt I could live with,what I wanted MY FE to be & it made me feel good about it and as many cabins as it was (& over two hours of deliveries),I still felt I did the right thing...
Two married adults shared postcards,magnets and a votive candle holder that I placed a Fantasy MV sticker on
Two Adults sharing a room, each adult received their own set of above gifts(which were all done thru Vistaprint)
Each child received their own set of gifts which were age appropriate,some acquired at a dollar store,Disney outlet, Homegoods,Ross Store,etc.
I did not give out candy. As for the childrens gifts, I found it easier to come up with ideas for the younger children. I thought the older children presented more of a challenge.
I don't like to waste money,so I wanted each gift for each child to be something they could/would like to use,such as Disney Coloring book w/crayons,or a few sand toys,or swim googles, or small magic kits,etc. They weren't extravagant gifts,just,hopefully, fun & useful.Hope this helped
