September 2016 cruise Harmony of the Seas. From Barcelona.

My wife and I are taking our first cruise next year as its my 50th birthday, she has also mentioned that should the situation arise and we meet a nice couple, she would allow us the chance to swing for the first time. We have spoken about swinging but never went further, so hopefully this time we will meet a couple that can help us get over the initial nerves, so the question is
Are any couples going to be on the Harmony of the seas when she sails from Barcelons Spain on 18th September 2016 and would like to meet up with a First time cruise/swing Couple from SCOTLAND.?
