Thanks for responding Rev,
Our TA advised us that HAL is stepping up enforcement of the dress "suggestions".
However, as our documents contained no special mention, I wonder what they will do if a passenger says that they flat out do not have the "suggested" clothing.
As far as a tux for me.....we have reservations in the Pinnacle Grill for all nights except the 24th and 25th. Those nights will be glued to the TV in the sports bar.
