I'm just back from a 2-night pre-inaugural "cruise to nowhere" on LOS. As far as I can tell, it's pretty identical to Freedom of the Seas -- which means awesome!
It's amazing to me that the ship can hold so many people, yet I didn't see huge crowds or lines at any venue. Plenty of seating in the showrooms, no long lines at the buffet, etc. Embarkation was relatively painless, too.
The ship is great fun, with lots going on at all times, wonderful facilities, attentive service, huge fitness area, etc. I wish they didn't charge extra for things like Pilates classes and other fitness related activities.
We just ot back from Freedom. WOW! To address all the comments.... I think the boxing ring was put there more for the kids on board than for adults. (They wouldn't let my husband & I in it at the same time) The 'squeeze' was used quite alot. Probably more for beer than juice. As for lines, the only time we had a problem with lines was when we had to be tendered back & forth. Especially in Labadee. The line for the tender back to the ship was ridiculous. They could have thought that one out a bit more. But WOW what a ship!
