Suites in row 2 are closer to galley where the flight attendants prep food and beverage service for Mint cabin.
Suites in row 4 are closer to the self serve galley and the lavatory. Maybe it’s just me, but I swear you can sometimes catch a whiff of that lavatory after someone makes a deposit. 🤢
The suite space in either row (and either side) is the same, I’ve sat in all four suites ... however row 1 actually has the most room for your feet when sleeping flat, but there’s usually someone next to you.
As far as food goes, have your friend check the menus on the first of the month they’re traveling. If it doesn’t appeal to them, they can call 1800JETMINT to request a PlaneEats meal ... however I’ve had friends and seen a passenger who didn’t get their meal request honored, seems like catering didn’t get the order or neglected it.
Have fun in Disney and hope she enjoys the Mint experience!
