There were no fireworks the 3 years we spent NYE there. In fact they were some of the quietest and most enjoyable NYEs we have ever had!
We sent the kids to the teen party and just made a nice dinner for ourselves in the villa. (We've never cared for driving on NYE if we can help it; too many crazies out! ) At midnight we usually step out onto the porch to enjoy the New Year and saw others doing the same. Some yelled "Happy New Year" and a few had party horns.
A few weeks ago we were at HHI and they had moved a huge barge out into the marsh waters for fireworks, but we had bad weather. They told us that Disney keeps the barge out in the waters for fireworks all through the summer. Don't know about NYE though... I would be surprised if they didn't shoot off fireworks at NYE.
