We just returned this evening from the 4-day Wonder New Year's Eve cruise. What a wonderful trip!
A special dinner was served in all dining rooms. Most men wore a tux, although many also wore suits. Most women wore cocktail dresses.
There was a family party in the atrium which was unbelievable. They set up two huge screens on which they broadcasted events going on all over the ship. Disney served complimentary champagne and sparkeling cider as well as finger food. I was worried that it would be too kiddie, but I was proven wrong. Music was playing, people were dancing. It felt like an upscale celbration. There were special parties in most of the bars as well.
At midnight, they dropped balloons and confetti. Disney also distributed a lithograph, special chocolates, and champagne glasses to all of the cabins. It was my favorite New Year's Eve to date. I can't recommend it highly enough.
