Hi: We sailed the Magic in her maiden year and haven't been back on a Disney cruise since. Our DD is 5 when we sail the Dream in April. I have been reading about FE's and door magnets and Princess costumes. I am not too sure what all this stuff is for. If you can provide me some high level information about these, that would be great. Will everyone have them and my dd feel left out if we don't have them? We are Disney lovers but very low keyed. Do all the girls bring a princess dress along? Any guidance would be appreciated. I know everyone has their opinions but just not sure if we will be in the minority if we don't do stuff like this. Thanks...T.
