Thank you for your perspective.
I think the upgrade from Ocean View to AC Verandah has two dimensions. (1) What is the Verandah upgrade worth to me? (2) What is the Aqua Class addition worth to me?
Looking at MoveUp, Verandah is at ~420EUR pp. Aqua Class is ~200EUR on top.
200 EUR for Aqua Class sounds like it's worth it. We would reduce our specialty restaurants dinings from 2-3 to probably 1 (Le Petit Chef) and do value the more intimiate setting of Blu vs. MDR. So moving from Verandah to Aqua would be a no-brainer for me.
I guess it's more that the (420 x 2) 840 EUR upgrade for Verandah is not really worth it for our style of travel as we have so many land days where we will be out and about during the day, get into the room to change & shower and then head to dinner and drinks afterwards. Once back into the room we'll go to bed to get up early again for breakfast and then the next land day excursion.
