We booked a balcony cabin, but we were lucky and got upgraded to a Junior Suite. Because our cabin was wheelchair accessible, it was even bigger than a regular JS, so it felt huge to us. Apart from the extra space, the other benefits were Suite check-in, bigger balcony (with 2 sun loungers and 2 chairs) and a walk-in wardrobe.
We also liked Sorrento's Pizza place on the Promenade for a quick snack (this venue is only on these larger ships). The rest of the ship felt familiar as many of the Royal Caribbean ships share features, so even though Liberty of the Seas is bigger, we didn't have much problem finding our way around.
Liberty of the Seas has also just undergone some upgrades (adding features that are found on the 2 newest Royal Caribbean ships). This resulted in the addition of the Cupcake Cupboard shop, Saturday Night Fever show, a big screen by the main pools, a 3D cinema and touch screens for information on each deck. All the improvements were great and the show had fantastic staging and choreography.
Of the ports we visited we enjoyed Barcelona, Villefranche (where we took the train to Monaco) and Naples. We took a private tour in Naples (not a very pretty city) to visit Pompeii and drive the Amalfi Coast with stops in Positano and Ravello. This is a really beautiful part of the world and although we did a lot of driving, I would recommend getting out of Naples. Pompeii was extremely busy - but this might have been because it was a bank holiday in Italy when we visited.
> Lovely ship and well maintained
> Excellent My Time Dining wait staff (David and Agong)
> In the Air, Encore (ice show), Saturday Night Fever and 3D cinema - all worth a look
> Wheelchair accessible staterooms are bigger than normal Junior Suites and we had a double-sized balcony which was great
> Late Departure Program was well worth the extra money for a relaxing morning on board and a final lunch in the Windjammer
> Our bathroom was wheelchair accessible, so it didn't have a shower cubicle or bath, it had a shower area with curtains. No problem in that, but the water never drained properly and always ended up in a pool in the centre of the bathroom which needed mopping up.
> The cruise line charged too much for its transfers from the port (e.g. Toulon). You can walk into a nearby town with a fantastic local Sunday fresh produce market in 20 minutes or take the tourist train for EUR3.50 unless you really want to pay to go into Toulon, but a taxi would be cheaper.
We went to look around the Duomo but the queue to climb the almost 500 steps to the top was too long so we went to the Boboli gardens for a fantastic view of the city.
We tried to save money by doing the audio tour in Pompeii but it isn't easy to navigate the site and they had run out of maps. We saw lots of interesting things but we had trouble finding the plaster casts of victims which we would have been disappointed to miss.
