I was on the Wonder in April and I agree - very shaky in some parts of the ship, particularly in Tiana's Place. I can't speak to how it affected me getting my land legs back after debarkation, as I always experience some degree of "mal de debarquement" syndrome. This time it took about a week for me to stop feeling like I was still on the boat.
ETA: I also fall in the precise demographic of people who are likely to suffer mal de debarquement symptoms - I'm a woman between the age of 30 and 60 and I have a history of chronic migraine, which has been linked to mal de debarquement in some studies. I haven't really met anyone else who experiences it to the degree that I do.
