Yes, Food and Entertainment Included.
Some newer ships have specialty reservations only supper clubs, which is an extra charge.
Except for Sodas, Alcohol, or Special Coffees, is pretty much covered.
The only thing that would need to be ordered is Room Service, and that is included also. The Buffett is served 3 times a day, with Pizza 24 hours.
In the formal dining room, times are set for your assigned seating. They have a menu for each day that you can order from. Just like in a restaurant, but you need to be there on time for the seating. You don't have to show your Sail & Sign card except for them to find your table for you.
But to sum it up, unless you want to go to the special supper club it is all included
You both can believe it
