CHIPMUNKS

We have booked to go to Rome in about 4 weeks on a train from the port, a P&O trip. Anyone know the chances of getting in the Vatican in the morning or should we look at pre-booking tickets? The P&O trip to the Vatican goes to lots of places we have already seen so opted to wander round on our own this time and take a chance with the Vatican queues.

Can anyone tell me if a balcony cabin with a sofa bed and a pulman also has a double bed or does it have to be 2 singles. Also is the balcony accessible when the sofa bed and pulman are made up for the evening? Also in a balcony cabin with 2 pulmans the only option online with P&O is 2 single beds but it does say that this can be changed to a double on request. Anyone know if this is correct? My son, wife and 2 children are looking for the best configuration with access to the balcony once the children are asleep, if this is ever likely to happen!!
