The 3 and 5 years olds won't as well, at least not for very long.
if it's the only ship they ever go on, then maybe....or maybe not...or maybe it won't be the only ship...
but we don't really care if they remember or not..
this past summer (2017), we all spent 3 weeks together at SSR in WDW...
i'm not even sure how much the 2 year old (the one who'll be 3 on the cruise) remembers of the trip at this point, only a half year later..
though mickey/minnie et all did make a huge impact on her..
the 4 year old (the one who'll be 5 on the cruise), does remember at this point...but in years to come? who knows..
it was a fun trip regardless of whether they eventually remember or not..
it was actually a very difficult trip for them and their parents....flying halfway around the world is no walk in the park with wee ones...
but everyone decided to go as you never know what tomorrow will bring..
and wouldn't you know it....we got back and i was diagnosed with cancer....so you see? don't put it off, no matter how young they are..
