This is all very interesting. I too don't tend to get seasick, but my partner can - it was definitely a tradeoff between the balcony 4 decks higher and slightly forward, vs the ocean view on deck one slightly aft. For a TA I wouldn't have thought twice about the higher slightly forward one, as we've done several and been fine. But for the TP, I settled on safe.
I do the ginger thing as well (tend to grab ginger from the sushi bar!) but will now travel with BOTH types of seasickness meds for the TP just in case!
Love this whole conversation - I learned something!
