My boys (16 and 14) are actually looking forward to the formal nights - they want all three of us in tuxes. Imagine that! They were against dressing up initially, but they have looked at cruise brochures, websites, etc., and decided that formal night means formal wear.
Of course, the 14 year thinks I am going to let him get a lime green tuxedo
The compromise there is - two formal nights. First night, all black. Second night - black suits, but everyone gets to select a fancy bow tie and cummerbunr or vest. So.... we shall see how this all works out.
I'm looking forward to the photos.
