Firstly I would like to point out, if you see my other reviews they are all positive and indeed all of my Trip Advisor reviews are the same, therefore for me to be annoyed it is pretty poor.
Joining this cruise ship in Rome is a no no... Unless like it us it was the only option for the dates we had.
If you join in Rome you have issues with regards to Casino Tournaments, the ships venues close in Barcelona to suit the main joining guests (small niggle), etc etc.
Our Room was 9295 - Aft Balcony Cabin which we paid over £300 extra each to have, whilst it was nice to be at the back of the ship for the romantic views etc, the room shakes like crazy and it is VERY SMALL. I could have paid £200 less each and got a larger balcony and would have been much happier, however didn't quite realise how small these rooms are!! I am 6ft 6" and my wife is over 6ft also, it was a faff to get around each other and the toilet was very cramped. Worst bit was the bed, my feet dangled over the bed by over 1ft!! Often woke with a bad back, which i don't normally get at home or on any other ship we have sailed on.
