We tried the dance cruise. It was a fun time, decent music, the drink prices were less than I expected. The ship starts out by heading onto the Cuyahoga River and you get to see all of the bridges, The Flats, Tower City, and The Jake all lit up. Afterwards they take you back onto Lake Erie where you get a spectacular view of the Cleveland skyline.
There are three different levels. The lower level had a live band playing the songs that have been on the radio for 20 years. This is where most of the 40 and over crowd were hanging out. There is a good sized dance floor down there. On the second level is where the DJ and the younger crowd stayed. In the front of the boat there is a seating area where you can't really hear the music for if you just wanted to relax. On the top level is a bar with a much shorter line than the other two.
I will definitely be back to try a narrated cruise!
