My biggest beef with the piano bars is that because the venue is so intimate, it is really easy for a few cruisers to take the whole place over. I have been on cruises where the same 8-10 people show up before it opens every night, take all of the good spots around the piano, fill up and submit a bunch of request sheets right away, and otherwise monopolize the bar for most of the evening. One my most recent cruise, they were holdovers from a B2B. I can't really blame the musician, because he is getting tipped, but once in awhile it would be nice if he said, "I will get to your other 15 Billy Joel song requests in a bit, Larry from Houston, but first I am going to play a song for Stacey from Las Vegas in the back there".
