We were on Liberty of the seas for western Mediterranean cruise on 07/16/11. This was our first cruise ever (for our very much delayed honeymoon) so we didn't know what to expect of it.
The first time we saw the Liberty of the sea while driving into the port "OH MY GOD! LOOK AT THE SIZE OF THAT SHIP!" even though it's not the biggest ship in the world anymore, it's the biggest one we've seen in person (until we saw NCL epic few days later).
We arrived at the port around 9:30am because we wanted to beat the rush and waiting long in the line, but turns out they don't let people in to check-in area before 10am, so we waited. Check-in was quick but I think we had to wait about an hour just to get on board for whatever reason.
Lots of storage rooms, and very quiet unless upstairs neighbor's kid runs around like wild buffalo.
