I have just booked my very first cruise (so excited!!!) but I didn't realise that the cabin wouldn't be assigned to me until the day of the cruise. I am worried that because of this we will be given a 'leftover, unwanted' cabin which might make the difference between enjoying our cruise or not! We have booked a guaranteed balcony cabin but still have reservations. I have been in contact with the agent who can offer us an assigned cabin for an extra charge. Funnily enough, the cabin number she quoted can't be seen on the Navigator of the Seas deck plan. Should I be worried? Has anyone else had this experience? Thanks.
