I agree, it would be nice if they told you what night the formals were. Then you could plan your dining options around that. Some folks like them but others might want to stay away from the regular dining rooms and enjoy a little quiet time in a Speciality Restaurant away from the glitz and glamour of the formals.
I've always seen on the websites 2 formal nights on a 7 day cruise or 3 on an 11 day cruise etc. Does anyone know if they actually tell you what days they will be on? Thanks.
