8690 have a door instead of sliding glass doors. The cabin on deck 10 on the corner. 1388 if you can get that get it. Its the best there is. If you decide on the aft try not to get deck 6 or 7. The balcony is nice but there is a lot of in the way stuff.
The balconies in the aft tend to step down. THe people above can look down into your balcony but can only see you if you are standing at the railings. The balconies on the aft will hold 2 lounge chairs. 2 regular chairs and a table and still have plenty of walking around room. THe cabins on the side hold 2 chairs and a small round table.
Its up to you if you want space or privacy.
