I was thinking that too...it sounds like they've been planning more Lido events on the 2.0 ships so there should be lots of opportunities for dancing. There's a dance floor in Limelight Lounge and Ocean Plaza shown on the deckplans. Who knows, there may be a disco just not shown yet. The Havana club and Asian restaurant listed in the article above aren't on the deckplans yet. I'm sure you'll have plenty of opportunities for dancing Floatie! I'll check it all out for you in November and let you know.
