If you noticed my quote I modified the poster’s comment to vegan. You can see the separate vegan menu in the current/old version of the menu in the app on ships which still have that or you can see the vegan choice in the new/future menu (like Symphony).
On the next cruise, if you want save and perhaps share the Compass later, use the numerous QR code links for it around the ship. They format and look better and it’s perhaps easier than taking pics of the paper version.
It may depend on how many others do the same thing, sailing capacity and how many traditional early diners show up. Currently on Navigator and folks with MTD, for which the earliest official slot is 6:45, are being seated as early as 6:00.
