Does anybody know which cruise lines have lounges, clubs, or events with ballroom dancing (smooth or latin)?

Cunard line (QM2, QE2, QV) have a ballroom which is the centerpiece of each of their ships.

They include daily at-dea ballroom lessons and dancing to a live orchestra each night. A professional dance couple is on board to provide the lessons and are available for privates.

Four nights out of seven are balls (ie Masquerade ball, Nautical ball, Captains ball, Black and White etc) where dress code is formal.

The ballrooms are beautiful. They even have afternoon tea dances each week.

I just checked out the Cunard site, and it looks amazing...very high class! However, the prices are a little steep for our budget, and we were looking to go to Alaska. They don't have anything going out to Alaska this year. Thank you so much for the recommendation though!
