We went last year and it was a great day out. It was a hot day and I had a lovely cold beer while walking along the quays (felt like I was in Spain) and we had the kids with us who were eating hot dogs and ice creams. There was music, entertainment and a real party atmosphere but very family friendly. There was a fun fair with rides (which you pay for) and we all got to go on the ships too(some of that is free). Be warned that it can be expensive but we really enjoyed it and would recommend it for a day out.
