We were on the Liberty last December and it is a beautiful ship. Identical to the Glory which was our first cruise so I felt like I knew my way around. The only thing that is awkward is getting to the aft dining room because all of the decks do not go straight thru....other than that it is beautiful.
We had an absolutely wonderful bartender at the casino bar. Her name is Emma and she is still on the Liberty. I am not sure if she is still at the casino bar but I would think she is. If you see her, can you tell her that Deb said hi and I miss her! I just emailed her back today but she would be shocked if someone walked up to her and actually said it!
You will have a great trip, the food is fantastic too!
I think you meant that you are sailing in 09, right???
