“On the Magic Class, I’d recommend the 2As. These four staterooms have a slightly different layout which puts the twin pull-down bed in the living room instead of in the master bedroom like the 2Bs. I greatly prefer the master bedroom to have its own closed-off space, especially when you’re putting children to bed early.”
The balcony is also longer on the 2a.
You’ve only told us the numerator, “$1000” but not out of how much, nor over how many days. I’d break it down to per day and ask if that was worth the additional privacy. Ask your spouse they may have a different point of view lol. It is a vacation.
