Hey Cruiser's I could use your advice! I want to go on the Navagator of the Seas, and my TA told me that the aft cabin verandahs are larger, but neither she nor RCCL could tell me which cabins they were.
Here are my choices,
CAT DB : 7388/7688
CAT DA : 9690/9390/8690/8390
CAT D1: 1688/1388
You can probibaly find out what those cabins are like at this site and if they don't list Navagator, the deck plans should be the same for Voyager, Explorer or Adventures.
Hope this will help you decide:
1688/1388 are the most popular cabins on voyager/explorer and has the largest and best balconys.
All the aft cabins have larger balconies than the ones on the sides, but the view is better the higher up you get. Also 1688/1388 are larger than the other aft balconies.
Go for one of them and you will be very happy.
