Oh, I read it as "departure day" meaning the last day of the cruise when you are departing!!! Embarkation lunch can be at either Cabanas or Enchanted Garden on the Dream/Fantasy. We actually found EC to be soooo slooow. The line took forever.
And I'll just throw this out there that on the last day you can eat breakfast in your assigned MDR or at Cabanas (our favorite on last day as not hectic at all if you go early). We go to Cabanas, eat a nice breakfast, head back to our cabin before 8:00 (the time you need to vacate your cabin), grab our carry ons and head off the ship.
