We, my hubby and I were on the Liberty last year for B2B for our anniversary, the ship is great - we took in all the shows, the comedians were a blast - and don't miss out on the Art's Steakhouse - what a fabulous meal. I think I read somewhere that since the 2.0 upgrade that the Liberty now has a Serenity area - did not have one when we were there so couldn't tell about this. Did hit the spa - enjoyed that, we were on the Panarama Deck close to the Lido deck - hubby also did the behind the scene's tour on the last sea day - it was about 4 hours long and he had a great time with that - you get to go down the hallways marked crewmembers only - if you are interested in doing that piece of advice - book that when you get on the ship at the excursion desk as it is a limited tour, - I think it was about $95. Hope this helps you out. Enjoy your cruise.
by the way - where in Alberta are you from - we are from BC - the South east corner of BC - about 1 1/2 hours away from BC/Alberta border.
