Hi there...OP again...can I ask about sea sickness? This seems to be the deciding factor for whether or not we cruise. DD22 may join us now and is very concerned.
I have a dd with SEVERE motion sickness that rears it's ugly head whenever it darn well pleases regardless of whether it is logical or not to do so.
Her first episode was on a transatlantic flight at a mere 17 months of age. Then her next episode that I recall was in 2004 while we drove up a mountain in New Mexico to go to a ski resort called Ski Apache. It's puts Expedition Everest to shame.

That was when she was 26 months old. Now--on her trip to Hawaii at 23 months of age earlier that year...no issue. (it was a particularly strange travel year for us as I type this out---BUSY!)
Okay-- then at around 6 she starts getting car sick on 15 minute trips. Then sometimes on long distance trips--some times she is good and some times she isn't. Okay--we began stocking the car with dramamine. She just let's us know--and she takes a pill and it keeps it at bay. We only pre-medicate if we are doing a long car trip.
Well, in 2007, we go on a cruise and I think NOTHING of motion sickness and we got lucky. She didn't have an episode. then we did a
DCL cruise a few weeks later and the seas were very very very different. It was like Mr. Toad's wild ride. (not typical--just something that occurred coming in and out of the Port until about Miami in the month of September---2 weeks prior, the seas were not like that). Anyway--she puked in the kid's club and almost got quarantined by the infirmary until I told them about her history and the fact that the CAPTAIN himself had warned the crew and had barf bags set out all over the ship and adults and kids of all ages were getting ill.
Now--I'm not trying to scare you! She had dramamine after that and was fine. But--it took very very serious seas before it was an issue. And my child gets motion sickness quite a bit.
I also needed dramimine on that cruise--this was not DCL's fault though. So weird.
You can also take Bonine, I Think--it comes and goes for us as far as being able to find it--so we usually take dramamine as we have trouble finding the bonine.
But people with motion sickness can sail, you just need to be prepared for it.
For someone who can get motion sick--it is always possible on a cruise vessel. But so long as you do what you can, you can sail successfully.
